Just wanted to know whether bait&switch still works with facebook?
sure..but it won't last long
Sooner or later FB will come back and review your ad again. Especially if you're getting a high CTR or if users are reporting it. You either need to have some type of cloaking in place to handle this or you're going to lose the account. Unless you have an endless supply of FB accounts and really don't care about losing them, I would not recommend the bait and switch method.

2088 pretty much sums it up.
If your looking to do big volume and longterm, bait and switch will barely work.
If your running something that is mostly whitehat and no crazy volume, then you may sneak it by for a while
Why don't you get polar's cloaker? It can be installed on any domain and on as many domains as you want. I know you're having IP issues. You tracker IP/domain will never need to change, even with new fb accounts, just your throw away domain IPs need to change. I think you are making enough money, that it will be a minor investment for you.
Haha its too ghetto bro, you will get stumped out with in an hour or even less. Facebook is a lot smarter then that haha 
There are a few cloakers in circulation man, one of the best that I can vouch for is Polarbacon/Tijn's message either of them see if they have a space. Otherwise get in touch with some Facebook runners I'm sure they know what the go is
From what I know , PB's is the MacDaddy of them.
no, but if you have too many account, you can try.
Lol I'm still doing it on multiple accounts, not going to say what, but I've been running for about a month across a few facebook accounts and I haven't been banned on any. I've even got retro dissaprovals and they still didn't ban me.
