Is it Okay,to randomly select someone and messege them!?

That's a bannable offense.

Yes, that's how I've made a couple of good friends here

All the perverts on here think so.

Why not?

Sure! How else would you get to know someone?

I can't see why not. Some people don't post publicly so how else are you gonna interact?
