There is currently a tiny bit of uproar over at r/irelandshittydrivers. A user took a photo of a work van that blocked two disabled spots. He sent the photo via Whatsapp to the company, which responded in a batshit crazy manner (for some reason, escalated it to praising Osama for 9/11). Naturally, the user posted the photo and the conversation to Reddit. Within a few hours, the company contacted Reddit and had the post removed. If a company with perhaps three customers per week can do it, what do you think large companies can do? Censoring user posts would be only the tip of the iceberg.
Form yor own opinion. This is the original thread. A follow-up thread claimed that it was removed by Reddit admins because the picture of the van showed the company name and phone number. That thread included the fan with blacked-out identifiers and was allowed to stay up until users didn't start identifying the company in the comments.
