Q.) So what happens if I get banned?
A.) Great news: you get to keep playing Titanfall! Less-great news: you only get to play with other cheaters. You can play with other banned players in something that will resemble the Wimbledon of aimbot contests. Hopefully the aimbot cheat you paid for really is the best, or these all-cheater matches could be frustrating for you. Good luck.
Q.) If I'm banned, what happens if I make a party with my non-cheater friends?
A.) When anyone in your party is banned, then everyone in your party will be treated as banned for that play session. If you are a non-cheater and you invite a cheater friend into a party, you will be stuck playing against cheaters. If you stop inviting your cheater friend, you will once again get to play with the non-cheater population. You do not get permanently tainted just by playing with a cheater - you are only banned for cheating if you are actually cheating.
