If not could the app be updated to include a block 'X' posts without removing all words with the letter X in it?
Yeah I tested it myself and I guess we'll have to put in a feature request for a new type of Keyword Filter that only removes whole words instead of anything containing that word.
Unless you have to use the platform, there's always an option to leave. I found it very liberating to no longer be a part of any social media (except lurking on Lemmy). Give it a thought 🤔
