It would be nice to have the ability to blacklist rigs manually
Done: https://github.com/Toorop/betarigs-autorent
Just add a file named "blacklistedRigs.txt" (in the same directories as the app) containing a list of rigs to skip (one per line).
I plan to add a "paranoid mod", which automatically skip never rented rigs & rigs with bad ratings.
No ETA for this option, i'm currently very busy.
Enjoy
