Image related is unfortunate. Not uncommon for jannies and mods in any website to use their power to self serve. It happens even in more serious and regulated sites like wikipedia, so I'm not surprised by the lack of moderation neutrality in a meme site.
This isn't just a 1 off thing by rogue moderators is what I'm trying to point out. This is a constantly re-occurring thing. I also experienced the same issue multiple times until I got fed up with it and stopped posting there a few years ago.
Their main moderator had a goal to make 4chan politically aligned with his views. 4chan used to be free speech but it really isn't anymore.

I used to get an ip block ban. But asking for my email to post in 4chan is just proof of how much it has changed.
