5 numbers have contacted me recently since my number ended up on the internet and this number was one of them. Who is this?

I just got a call from them also, along with several others. I don't have a clue who they are or where they're from.

He or she sent some random, pointless texts. I got a text from someone on 4chan.org right before receiving this text, so I assume someone posted my contact info again. I don't really get it. I'm told that they are trying to "troll" me, but it kind of boring.
