Please note: You as a campaign will not be warned or have your signatures removed for having a handful of low quality posters on your campaign especially if they're quickly dealt with. We accept that no campaign will be able to stop spam 100% of the time but these guidelines are there for the campaigns where it becomes blatantly obvious they are doing little to nothing at all to try prevent spam and are happily paying people to post rubbish continually even after a warning. Please monitor your users closely and there should be no issues.
Stake opened a thread for reporting them and is dealing quickly with it.
So where is the issue?
