Is it true that new customized audience ads in Facebook aren't getting approved?

I'm hearing that customized ads targeting Facebook users UID's are being denied. Can anyone confirm this?

And if so, what are some possible solutions?

No problem being faced in custom audience. I don't guess anyone should face a problem in this, as it is one of the major feature used by us.

However, creating custom audience based on their first or last name is one of the multiple reasons. your ad was disapproved.

I am wondering same thing... I also am hearing this.
