Isn't Merit some kind of "like" or "I like this" and I can return them back? I am surprised there is a whole tread talking about me for this.
If any of the members you sent merits to posted this, it would make sense as it explains why they sent merits back. But, being posted by you, doesn't really make sense (you're not supposed to know how others think). Sounds like you're looking for an excuse to justify it!
Anyway, imo, this is not a tag-worthy offence. At least not with the available evidences.
