, but my advice would be to just leave it alone--and not because I'm trying to protect people who abuse the merit system, because I think that's a slimy thing to do. It would probably just be a waste of your time
I think that's the only risk you run right now, a waste of your time, you could make the thread accusing the accounts you claim are connected and there is a very high chance that nothing will be done to them, as merits is a subjective matter.
You may only end up raising "dust" and this may be unnecessary, you definitely wouldn't be red tagged for opening up on your claims.
Most times for merit abuse to be effective for the abusers, they must be of a high rank, to have enough Smerit to distribute and rank up the account they want to, for this to be done, a crazy amount of merit has to be given, if this is not the case which it hardly is, it's better to let sleeping dogs lie.
