Are there any downsides to installing TMUnlimiter mod?

Particularly stuff like getting banned, being unable to play with unmodded players, etc.

I've never seen someone getting even kicked for using unlimiter. The only thing I have experienced is that Unlimiter may crash on some tracks randomly. Also unlimiter usually doesn't launch with a Steam in-game status.

If one creates courses with pieces from other scenes (like using Rally pieces in Island for example), all players wanting to play online with you must use TMInfinity.

However, courses made in TMInfinity that do not use other scene pieces will still work in Vanilla TMU/F...supposedly. It's possible that other modifications may cause incompatibility/crashes but not one hundred percent sure on this.
