I'm pretty sure it's 3 or more unintended negative ratings to make it count as rate abuse (that's what I heard from)
Rate Abuse As defined by Blooberry the waffle. Rate abuse is when a player randomly rates a player's posts negatively multiple times in a rapid succession. Ex; Bob: (Productive and friendly stuff here) Mean Person rated this dumb. Joe: (Perfect spelling and helpful stuff) Mean guy rated this bad spelling If someone did this multiple times within say, 24 hours it would be considered rate abuse. THere is also positive rate abuse where people make an alt account and grind positive ratings. This will most likely get both accounts perm banned if they are from the same IP (Thus proving they are probably the same people)
Quick Question: If you gave positive rates to someone that wrote negative things, technically your abusing it, but would you "the authority" consider it as abusing the ability of rate ?
