DEAR (again) someone report this question so a moderator can see it.
Are you ever going to do anything about these bots?
Someone made bots and are trying to infect other peoples' computers by claiming its an answer when it isn't. The link leads to a download to a "PDF" file. (it's not.) And these accounts keep answering questions and mark them as unanswered, and could trick people into infecting their computers.
They're taking over this site, please do something before more peoples computers get destroyed.
