i think a blacklist-proof submitter would be really cool, autosubmit tools are sometimes abused and i got blacklisted at some "medium" TGPs for using them (can't read the rules of 1000 tgps sorry
) , 2 ways to implement this comes to mind:
1) by asking TGP owners permission to add their TGP to your database, and or
2) having your own blacklist (databse on your server) where tgp owners can report cheaters, if you get a lot of complaints about a particular user it gets banned.
Anyway i don't know if this is good/bad for your business since you can lose some customers, but it would be the biggest autosubmitter so it wil pay in the long run
