This has been asked before, and I highly aware that this suggestion was rejected.
I’m suggesting this for a few reasons. First off, it was last suggested almost 8 years ago. Maybe things have changed since then. Second, I think it would benefit people a quite a bit. With people coming here just spamming and trolling, I think some people would prefer to just have a normal conversation in chat. This would also go for wall posts, since people can spam walls even with the post limit. Lastly, I personally want this, since some users (new ones, to be exact) sometimes really annoy me, and I wish I could just... well.... block them.
So, basically, I’m asking if there could be like a “Block” button or something on everyone’s profile. When you block something, you can’t see their wall posts or their messages in chat.
I hope this is taken into consideration.
