Bing Ads keyword issue

I'm using Bing for ads. Normally never had a problem with them. Right now they're disallowing my keywords "buy instagram followers", "instagram followers".

What's the problem with this?

If I use the keyword "followers instagram", which is eligible, will similar results show or no?

They may have blacklisted those keywords. I've seen it happen before.

You could try keyword variations that they may have not blacklisted, but it could trigger a manual review.

Research your competitors and see what they are bidding on.
