Hey! Basically, if you make a post on a thread which has been inactive for over 30 days, it's called as necro-posting. This is not allowed.

However, you are allowed to post on an on-going conversation such as Events, Community FAQ, etc.

Ok thanks... but I want to know why it is bad?

I think it's just to make sure that the older posts are not bumped, as it might be annoying and considered as spam.

The point is, if you need help with something on an old post, a better option is to make a new thread instead of posting it on an older one.
