If a DT member tags you for something stupid involving merit (ie. probably anything less than selling merit), then they're not going to be a DT member for much longer.
Guess I missed Theymos's take on this, and I'm glad you linked to this post, suchmoon. I haven't been tagging merit abusers anyway--certainly not consistently. There have only been a couple of cases of blatant abuse where I've given out negs.
Anyway, that's why merit abusers haven't been suffering any consequences, cryptohunter. I had a question about this myself a while back and
started a thread wondering if DT members should be punishing merit abusers, because I could tell it was being done inconsistently and wanted to help out.
There's too much subjectivity involved when trying to judge who's abusing the merit system and who just doesn't value something like 50 merits the same way another person does and would have no problem handing out that amount of merits for a post that most people would find mediocre. I don't know if I agree with Theymos completely about not tagging anything short of blatant merit sales, but if he doesn't want to make a big deal out of merit abuse I'm not in a position to argue.
Edit:
I only tag those users who are blatant and obvious.
It always brings a smile to my face when you drop some red on merit abusers, and yeah I suspect you're not in danger of being booted off DT for tagging these fools.
