They keep spamming even after uninstall & are siphoning me traffic

I am not impressed with the owner of this plug in. The sign up interface with the public is extrememly aggressive. I uninstalled it for that reason and asked the owner to remove me from their data base–WHICH THEY DID NOT!!! It appears they continue to try to siphon my traffic into their own data base for their own purposes. On my iPhone, I still get a pop up requesting my visitors to add themselves to “our database”. I have nothing to do with this database, however. I would steer clear of this one.
