I believe there is no need to report it to the moderators. They're not here to do the job of someone else (the campaign managers).
Even if they do it; moderating what? Is there a rule saying you're not allowed to post once the campaign is over? Nope
In any case, they are not the janitors because some are too lazy to maintain their topics (close it when it is no longer needed)
Complaint to the campaign managers directly.
I also don't think leaving neutral feedbacks is necessary. (Soon people will suggest leaving neutral feedback because you logged in.
)
Especially if the purpose is to help the next manager thinking to accept the user. It's up to him to do his job, without relying on someone else to put the spoon in his mouth.
Instead of leaving neutral feedback to the bounty hunters, what about giving a neutral to the campaign managers, saying something like, "too lazy to close the topic" "Accept spammers in campaigns" etc...?
Take your cojones and report to the campaign managers
