According to the mods, Bon Jovi is one of the most trolled bands on the site so it's not all bad, we just got the short end of the stick there. Lol.
When I once reported a show that doesn't exist they removed it within 24 hours (though the report was pretty extensive and included sources) so I can't say I have bad experiences with them in that regard.
That being said, I also mentioned how all of mefourni's edits are a load of crap and nothing was done about that...
The thing is they never check for sources when the edits are made by alleged attendees and in recent times they also started to care less about credible sources ('SRC: Tape' is accepted 99% of times). Truth is, a publicly editable setlist database is a failed concept in itself.
It is a great utility for providing the ability to start somewhere when researching concert dates, but never fully believe anything you see on there (unless it was made by me or hAnD90

).
