Correct; the problem isn't for tagging actual merit system abusers, but rather tagging users where there isn't enough evidence to support the claim.
So in this case, should we only tag users that we are strictly sure are abusing the merit system?
i.e. not through circumstantial merit exchanges of large amounts but rather threads or other media that voice merit trading/selling?
Seems like it'll let alt rings get away scot-free and will also let people who do off-site trading boost their merit.
I'm willing to retract some ratings that are circumstantial but I believe there are at least some that seem pretty absolute.
