There has been quite a surge of spam accounts on the site lately. These are accounts that open up and post 1-3 pointless answers with a link to some malignant site or another.
What I do when I notice this is go to the user's page, and proceed to flag all of that user's answers as spam. However, it has just occurred to me that this may not necessarily be the best way for me to help with this (as I'm merely creating a lot of noise instead of dealing with the core problem, which is the account itself).
So I was wondering, what exactly should I do when I notice one of these user accounts?
