Thanks for the replies guys.
I will consider what theymos said here:
Additionally, bumps should not be annoying, which needs to be determined subjectively.
and if I decide it's low value post will just report it.
Replays to genuine posts are fine. I keep seeing old style bumping services.
I suggest, if you see such project, inform the OP account first, because I've seen people fooled by those "advertising companies" to keep the project alive by breaking the rules and the owner has no idea about it.
I also would like an option to enable/disable my bumping power when replying on threads in such sections.
