Someone who's MS25 I flashed with 5.2d was banned over a week ago. He played some pre-releases and non stealth backups. Now his stepson also has a MS25 that I flashed with 5.2d as well. It was only on Live for 2 weeks in March this year. I know at least one non stealth back was played on Live during that time period. The stepfather played on Live a lot, while the stepson doesn't play on Live at all. I suggested for them to switch consoles. I could flash the one that wasn't definitely banned with ixtreme and see if I could get it on Live. Well I did that 2 hours ago and it's doing fine on Live, i.e. no ban. Also it's not playing non stealth backups as advertised and all the stealth ones are working that I tried. So after all this it seems to me, MS probably hasn't been logging since the fall update, but more like around month or less before the Spring update.
