And similar comments in the vein of "____ is following me! Argh!" or "Some creep from ___ is stalking me!" or "____ has be bugging me for weeks" are turning up on more and more of the twitter accounts in cases here...especially in about the tween to 30's age range.
Look at how many times "stalking me" has been said in the last hour or so -

It's equally common w/ "being stalked" etc. as well.
It'd be a pain to weed through "following me" or "being followed" since that also is twitter specific jargon, but there's a similar number to those along the lines of "stalking."
It's very, very, very rarely literal, and is extremely common "lingo" in a large population speech wise just as it is on SM.
