Welcome back Perk!
Not to worry!

You'll never be banned from FIBS for dropping (never that I've ever seen anyway). The saved games will go away all by themselves in so many days if you aren't able to resume them.
However, meanwhile, you should use repbot before you accept an unknown invite (tell repbot ask nick), use another tool, a command (show savedcount nick). You will learn to choose who you play with more carefully.

You'll learn who the good old timers are......and........beware of most phone users! You kind of take your chances with newbies where you tend to find a lot of droppers, not always for some reason of their own, but.........
Some fine day, you may have 0 saves!
