Promoting Sweepstake offers on FB

Anyone knows a right way to promote sweepstake and rmail submit offers in fb groups ? I joined a few groups about coupons and free stuff , but when i add my aff link shortened with bit.ly it shows community guidilines violation and post gets shadiwbanned .
Anyine knows hownto do it in a right way? Maybe to post uncklickable split link ? Bit this way users must remove space and input into browser...

Gonna give you another idea ,try other shorten service, or redirect with your own domain , etc.. a lot of ideas man.

I tried as a page redirect also , the same stuff , not shown due to community guidilenes . Seems the only way is setting prelander with a click .

You can put at first a prelander with a button to submit and after a time try to redirect the domain to the offer.
