How about participating in /r/Place and promoting the fediverse?

It could so easily be manipulated by Reddit in their favour - I can just imagine admins fixing themselves extra pixels so our areas get mysteriously vandalised. It's their game and their rules I think it's best to just stay out of it.

They they totally did this last time, and for something dumb too. Every post calling them out was also removed.
- and for something dumb too
  
  What something was that?
Yeah this whole thing just feels like a huge trap for them to try and lure people back in. "Hey remember how fun r/place was? We're doing it again. Come on back! Please clap."

the prevailing opinion seems to be that we should promo "fuck spez" and it is already underway 😆

While I wholeheartedly concur with the message, I am not sure that this is effective. Frankly I would happily accept thousands of people fighting to write "fuck marsokod" over a an image if that meant propping my shares by a few millions ahead of an IPO.

I think they're doing fine as is. We'll just drive more traffic to reddit if people on here who haven't joined yet start participating. The fact that they also force you to use the official app and new.reddit to see it (and probably participate too) makes it worse. I only browse the site using old.reddit so that's already a no for me.

I think we should write “fediverse” next to the Never forget 3rd party apps box.

I don't know this would work. Right now, I'm using my pixels to add more fuck spez. I suggest you do too. Anything more coordinated than that would require fishing people out from every site they scattered to. We're still pretty small.

nope... I'm certainly not participating in an act to harass people on the internet, not even /u/spez.
- Hmm. I see it as a failure of his own responsibilities. To each their own, I guess. The power imbalance is certainly going his way. Otherwise, it could be argued that his being shat on in the ama was problematic? It's a short message that encompasses discontentment pretty broadly. I think leaders need to be held accountable. To me, this is the equivalent of saying "fuck macron" or something, which is something me and a lot of other people do on a semi-regular basis. But behind it is solid criticism, and it's a shorthand for protesting being ignored, silenced, or denied democracy.

I would but my account was banned for “harassment” for insulting spez lol

Ditto

I had a look at r/place and you can only view/interact with it on the official app or with new Reddit. No thanks.

After giving it some thought, I think you should indeed do that. For Lemmy AND Kbin and more.
tl;dr: Advertising the existence of kbin and lemmy to random Reddit users is exactly what you want to do if you want to go against Reddit, and r/place is an excellent way of 1) telling people who don't know about it that these platforms exist, and 2) showcasing the vitality and size of the communities on these platforms

The major objection is that going to r/place gives Reddit the engagement and numbers they want for the IPO, and I think that's a compelling point but I don't think it's as obvious as the people making that point seem to think. The idea of "don't go on Reddit to protest Reddit, that's just helping Reddit" has some "But you live in a society, curious" vibes to it; I think the question of whether to protest vs abstain and how to best protest is always going to depend on the details of what you're protesting or abstaining from.

In this case I think Kbin and Lemmy users should put their names on the r/place board according to the following reasoning:

The argument that you shouldn't go on r/places is essentially saying that the best protest against Reddit is people leaving Reddit, which I agree with
Like all protests however it's not that impactful if it's a few isolated people doing it, you need to find a way to have users do it en masse. Coordination is key.
Same thing for going on Kbin and Lemmy and others - these platforms become good if they have enough users to sustain vibrant communities, they rely on network effects.
r/place as an event is a showcase of a community's coordination. It both requires a community to be large and well-communicated and it gives a very practical, visible way of advertising that coordination to both rivals and random observers (there's a paper out there proposing that this is why music evolved btw, hmmm that's pretty cool)
what ultimately made me decide to post this is going on the thread for r/place's first day. Look at the conversations, this is exactly what they're doing: discussing the communities participating, commenting on what they draw and explicitly talking about what it means for those communities' size and coordination
These comments also included people asking "why fuck u/spez ?" and "the only reason I'm still on Reddit is that there aren't any alternatives"
This means there is a pool of normie users who aren't aware of the protest, but are following r/places, and the "fuck u/spez" movement is effective in bringing their attention to it
By the same token there are tons of users who aren't aware of existing potential Reddit alternatives (one of those comments got "Lemmy" as a recommendation in replies and said "interesting I'll check it out" - they legit hadn't heard about it).

In conclusion:
Advertising the existence of kbin and lemmy to random Reddit users is exactly what you want to do if you want to go against Reddit, and r/place is an excellent way of 1) telling people who don't know about it that these platforms exist, and 2) showcasing the vitality and size of the communities on these platforms.

Now in practice I don't know that these platforms actually have the size and coordination to showcase that on r/places and that's fine, clearly a huge percentage of people here believe that boycotting Reddit entirely is more effective or more convenient. But if the question is "which hurts Reddit more, promoting Lemmy/Kbin on r/places or avoiding r/places", I've come to believe the answer is the first.

EDIT: oh right another objection I saw was "but the admins will just erase it", and there again look at the comments on r/place. Clear streisand effect on the guillotine, if there's stuff for lemmy/kbin/squabble that's visible enough and admins erase it it still works fine from a comms perspective.
