Yes, it is, but, the consequences of the OP's action will not only affect those cheaters but some middlemen as well, myself included, that's why I uttered my concern here.
Just because I received a lot of transaction from a lot addresses, often the same addresses, doesn't mean I'm the owner of all those addresses, but some people here don't and won't care, they'll just agree to that list, flag my wallet, then go straight to my profile and give me red trust.

The point of my rant is if you guys wanna point out cheaters, you better come up with a more solid proof.

Now let's see, will my address show up on the list or not.
