Congrats OP. I'd say some people are just plain jealous that they can't earn as much merit as you did. sMerits are pretty much limited by now and I don't think you have cheated your way to get that much merit. The fact is, I think everybody that gave you merit is conscious enough to decide for themselves if you do deserve to receive that merit. Looking at your merit, you received plenty of merit from people that would likely not give merit just for kicks.

Edit: Oh by the way, I think I just discovered xtraelv has been abusing the merit system. If DT members could check his merit summary you will see that he has been exchanging merit with user Lafu back and forth.

Edit 2: Well, I think OP beat me to it, I hope some DT members could check on this guy. Ref: https://bitcointalk.org/index.php?topic=3168616.msg37797512#msg37797512
