":)" Profile Status Spammers

[shadoom]

Hey,

recently I'm getting more and more spammers on my board which update their status everyday with a single ""
Their IPs are coming from Luxembourg, Poland, Sweden, Romania, and are listed on several websites for known spammers.

I was wondering why would they only spam a single "" I'm used to links to fake watches or medication and similiar stuff, but this?

Maybe it's just a filler value for that field. No particular reason.
