Is it safe/wise to post one's cell#?

[Hagglebaron]

I get alot of pm's from people requiring escrow service right away, and often by the time i check my inbox later on too much time has elapsed. Some have suggested i post my cell number so people can shoot me a text or whatever if they need me.

Is this a smart idea? What are the potential negative ramifications of doing so? Any advice is appreciated guys, cheers.
