I have posted a question and found myself surprised about a comment. (Check last comment to the posted question, the comment by the user who is called "asdf"). "asdf" is most probably a bot, and is giving out SE account details. If you check the comment, "asdf" posted a link as well. I don't know where the link goes to, and I don't want to find out(probably spam/virus). I flagged the user. Is this the first time users like this have appeared on EE stackexchange? I have never seen bot users before. Anyways, I flagged it as the "other" category and explained. It is obvious that it is a spam account, so I think it should be deleted. Any mods reading, can you please delete the account. And does anyone have any proposed solutions on how to block spam accounts?
