and who will define, an interesting post or not... this opinion is subjective. a lot of things it is interesting to me, but also it is a lot of not. here so then also it turns out that ban for anything...
Staff decide, but of course it is subjective. Staff aren't going to remove posts just for the fun of it though so it really needs to be a worthless contribution for it to be considered for removal. Lots of people report posts that they think are pointless and sometimes the staff agree and sometimes they don't, but users here aren't banned just for 'anything' and are done so for breaking a serious rule. This forum is probably one of the most liberal on the internet and in fact many would and have argued that moderation here is too lax.
Yes, agree. We really Appreciated and we thank for consideration. Sometimes our post has been deleted even though it is related to the topic.
Just because it is related to the topic doesn't make it relevant or important. Stating an answer that has already been given is pointless and should be removed even if you put some effort into the answer.
And also to those account that has been banned, We lost our activity that we've been working, can retrieve our accounts? Thanks!
Not if it's permabanned. However, you can create a thread in Meta requesting unbanning on specific accounts.
