There’s currently no repercussions for falsely right-click reporting someone. Whether we’re talking retail, or classic (especially), what place does this feature have in this game? I understand you can appeal, but that appeal process is not immediate.
So, we can expect:
Battlegrounds - a whole team reports a flag-carrier, or other difference maker, auto-disconnecting them. Win.
World Boss / Guild Rivalries - guild A right-click reports guild B while fighting a world boss - instant disconnect, maybe for that main tank or healer who are going after gear for progression. Guild A right-click reports guild B’s main tank/healer or other difference maker(s) before a raid, auto-disconnecting and preventing them from raiding. Such an easy way to win realm accomplishments.
Farming devilsaur or mining nodes? - Good luck. The “devilsaur-mafia” type groups did in fact exist, and likely will again. Don’t want that competition? Whole group right-click reports you, auto-disconnect. No more nodes or leather for you. Win.
Enchanters - selling your services in Org/IF? The competition can be stiff. Enchanter A gets his good guild buddies (the same ones he rolled on gear for in that dungeon) to right-click report enchanter B - silenced and/or auto disconnect. Competition gone. Win.
AH Competition? - happen to come across your lowly AH competitor in your favorite capital city? Right-click report and encourage your guildies to do the same. No more competition… by the time he’s back in the game your items would’ve already sold. Rinse/repeat. Win.
Questing - low spawn rate on those quest mobs mixed with a bit of competition? Just right-click report. If you have some friends around, have them do the same. Auto-disconnect and the quest mobs are all yours. Win.
World PvP - have a little 1v1 that turned into SS vs TM? Good fun. But now you can have your faction right-click report that beast on the other side that’s tearing everyone up. Auto-disconnect for him, more HK’s for you.
Etc. Etc.
There are so many ways this feature can and will be abused. To simply right-click report someone and have them auto-silenced and auto-disconnected is as easy as it gets when it comes to any form of competition in WoW. Sure, you can appeal, but you might get resolution later that night or the next day. How is that a solution? It’s not.
There are just times when a good old fashioned human are needed. This is one of those times.
