I am risking my only one account not sure if I am a fool or what? Only thing I am sure about is, what I am doing is right. These merit users needed to be warned and I am warning them with the proof of their misuse.
Then you shouldn't worry.
These abusers need to be tagged (red trust), they need to admit that they are guilty.
They won't do that, instead they'll come up with countless excuses...
Here's a post regarding that:
There isn't really any rule against it per se and it's not really enforced at an admin or staff level, so it's more of a community issue right now much like scams and other such shady behaviour. As far as I'm aware the only thing that is currently prohibited is merit sources selling their merit though I'm not sure what the punishment for that would be other than them being removed as merit source.
And this post is somehow relevant to this thread:
I think that tagging may be appropriate in particularly obvious cases, or particularly egregious cases involving hundreds of merit points and several posts. But generally you should start out by assuming good faith, and only change that opinion as the evidence really piles up. Tagging someone immediately after an instance of apparently-inexplicable meriting is too trigger-happy IMO. Even if it is a case of illegitimate merit, even hundreds of illegitimate merit points are not much of a problem IMO, so you have to ask whether it's worthwhile to possibly make a mistake by tagging someone who is merely suspicious.
