Okay, just to share my experience in case it would help others:
I was banned while using
@D3T0X's mod because I went crazy buying tickets and diamonds (in millions), haha. I was logged into FB when I was banned. So I deleted, clear cache, restarted my phone, reinstalled the same MOD, was successful in loading the game, conservatively (in comparison) bought about 8000 diamonds and 400 tickets. I didn't sign in this time, played as guest. I then discovered the wifi trick using version 1.5.4 and played for a loooong time using that version until it became stuck at screens with text messages. So I updated to a MOD shared at Sbenny's Shared Apps forum, and after that updated to
@bbwi's MOD. At this point, I realise that the Chapters saved game/information details is tied to device in some ways, I get back all my data when I delete and reinstall, even without logging in. Meaning if I am to get banned again without signing in, I probably would not be able to play without parallel space and similar apps, because it would always "bounce back" to the last no log-in data.
So I used
@Dellabrown's trick to log in using Google, and have been playing it with no problems using
@Sbenny's mod. This is in the case if I get banned again, I am 80% sure I can start over with a guest account. So I guess my tip for those currently not banned is to perhaps use some dummy FB/Google accounts to keep the option of the guest account open. Of course, this way you WILL lose your progress once you are banned, but at least there is still some way of playing still.
I hope this makes sense!
