A few months back, Twitter started testing out a feature that kept "VIPs" or elite users from seeing ads on the social network. It wasn't clear what VIPs were. It didn't seem to be about reach but more about verified accounts. Now, though the test for these special people seem to be over as Twitter is now treating them like regular users. They can now see ads like the rest of us. In Twitter's defense, they didn't announce this as an official feature but more of a test of sorts which the company likes to engage in every now and then.
