Right, so I received a wrong number text. I tried my best to catch them in their scam. This involved baiting questions and trying to be a little polite. Their English went from some of the most grammatically correct English, to absolute nonsense, to typing in Japanese. To make a long story short through my deduction I felt I should try to shock the scammers into never trying to contact me again. I used to stock photos on Google to try and placate their questions, but I got sick of it and just decided to up the shock value found a picture of a penis with syphilis and sent that. Then promptly deleted the text and block the number. I kept my girlfriend in the loop let her know what was going on while she was at a friend's house but I think she's angry at me after the fact.

TL;DR Sent a syph dick pic to a suspected scammer and made my girlfriend upset.

EDIT: Found out why she was upset. She was cheating on me. Trying to hide it by being overly mad.
