Don't get it, so why quote reply me? What does your statement have to do with mine?

Technically POA aren't spam but they can be used to spam and when you see such cases you do the needful, report the post and add an indication, it's an account used for thread bumping then the account would be nuked. The cases you mention is just a bump service which they could choose any mention to bump a thread but decided to use POA. You should suggest a solution to that problem instead punishing all junior rank members.
Lol you edited your reply,

. The suggestion might not be enough but it might do the trick, we have to try it out before we conclude.
