While going through some of the threads, I came across these accounts and wanted to understand if this can be called a Merit seller.

Then I also came across a Legendary account.

If we look at his Merit history, he dishes out 50 Merits to such posts, another post and ANN threads. Looks suspicious and also if we look at the recipient and the donor they have striking similarity. As if the same person runs both the accounts.

Is there a group that handles such queries like the SPAM buster group?
