It’s not working. What’s up with that?

These are the two referral spam links it wouldn’t let me add:
dp.g.doubleclick.net “Not Valid”
AND
forum.topic48053131.darodar.com “Not Valid”

If I read notes correctly darodar.com already existed so apparently I was already covered.

But the first one there was no doubleclick.net on your list

Hello,

We tried using this plugin on ~100 sites and had to remove it. For some reason, some of the sites began redirecting users to https://sharebutton.net/ after the plugin was enabled. Has anybody else had this experience? We are also testing SpamReferrerBlock and have not had similar issues with that one so far.

Cheers
