those are usually reported and if the OP is very ... persistent
he could be awarded with a lovely red tag as a merit beggar/solicitor
maybe bounty managers could be more selective and take more time picking participants
if the requirements were not just rank, but to have a good post history, there might be less spam and less incentitive for the spammers to
rank up if they are unable to get into a campaign , at least some of the managers are doing rigorous checks (not all ,sadly )
as for the local board merit sources, it is not always very easy to find a merit source who speaks both languages fluently (native and english), has proven he can be a good judge of the post's quality and will not go rogue
