Cloaking too! One that hasn't even been used in quite a while... strangely a 4th wasn't touched (even though it was created on the same machine / ip as the other 3).
account 1 - coreg / biz op (both biz op and coreg running)
account 2 - coreg / biz op (only coreg running)
account 3 - biz op ads but everything paused for at least 2 months
account 4 - no ads / fresh account only used for a few days several months before but i deleted the ads
all different credit cards BUT created on the same ip.
some of the biz op ads shared the same domain across the 3 accounts.
account 1-3 are gone. account 4 is ok.
i *think* it was my old biz op ads that got me... i've only been running coreg for about a week.
maybe this will share a little insight into how fb chooses to ban / link accounts... either way, it sucks. i was doing pretty good with coreg on it as well 
cloaking might work for approvals and high level / speedy reviews but when you get a nice thorough review like the one i got... it's bad news
