gta 5 money hack/glitch am I going to get banned for receiving money?

I was playing gta 5 online today and I received a LOT of money im saying at least in the billions from a player ranked 800+ I haven't done any glitches or been in to any hacked lobby's or done any DNS I just got it given randomly. I figured that there was a glitch going on as there was 5+ people with tanks so I turned my xbox 360 off and came back 2 hours later and I still had all of this money! I decided to spend it and bought some nice cars, clothes, hair cut, max weapon ammo and attachments, masks, tattoos and it didn't even make a dent on what money I have!

What I'd like to know is am I going to get banned, suspended or de-ranked and have to start all over? Technically I haven't cheated I was spending what money I got given I'd hate to be banned permanently or de ranked to level 1 as I have played this game for months I don't understand how rockstar is going to fix this problem I had 400k legit with the luxury flat I'm trying to avoid it all but it's literally every lobby!
