i really hate it when spammers tend to write very irrelevant comments. the common ones were:
i will give you my upvote because you were give. give me an upvote too. tnx
those people should at least understand how bad it is for their reputation . it tends to make my post messy and other's post as well.
I agree. It's just clutter, at the very least. And insulting at the most.
