Blue Star showing, even though no longer premium.
A Blue star is given to a player when they have either been gifted A$ by another player or have bought A$ themselves. This blue star usually indicates the member is a premium player but when their subscription runs out, the Blue Star stays put on their profile so it can give a false indication of being premium.
Ignore List has cleared.
If you uninstall and reinstall the game, or use a different PC / Lap Top / Device, the ignore list will have to be input again.
It is one of the few things stored on your computer rather then on their servers.
So before you uninstall and install again, or change computers, copy and paste your ignore list so you can input it all again.
Chat Log Record
For the same reason, you should also save your chat log if you keep it as a record.
