If you're getting long bans from targets it's because you're skipping too many - I boosted a lot of T10's on an Ironman, with 5 boosters all on the same IP and didn't have an issue, the only problem I had was people finding me / ragging me, make sure you take them out all the same time you should get atleast one of them as a target, make sure you turn off deep wilderness targets as well.
