Lol why would anyone post their phone number here
I will get the app not your number though....CUZ be bit whierd having strangers phone number.
Lol, 2 possibilities.
1. He is and hasn't realised the spam, miss call and general abuse he's potentially invited.
2. It's not his number and wants the owner (ex-bro/bf) to receive said spam hence the post still being active.
My 2 cents
