Note the inference at the last of this article. Seems to infer that the ADL can provide a church membership roster so that the UK gov't can keep any of them out of the country.

The British government has banned Fred Phelps and his daughter Shirley Phelps-Roper from entering the United Kingdom.
The Phelpses, whose protests at military members’ funerals in the U.S. have prompted lawsuits and legislation, apparently had planned to fly to the United Kingdom to protest a performance of “The Laramie Project.”
The play about the death of Matthew Shepard, a gay student who was killed in 1998 in Laramie, Wyo., is scheduled to open today at Queen Mary’s College in Basingstoke, Hampshire.
“Both these individuals have engaged in unacceptable behavior by inciting hatred against a number of communities,” a U.K. Border Agency spokesman told the Times Online, the online site of The Times of London. “The government has made it clear it opposes extremism in all its forms.”
The move follows a similar banning earlier this month of a Dutch government official for his anti-Muslim views. Geert Wilders was deported immediately after flying into Heathrow Airport.
The United Kingdom became aware of the Phelpses’ planned protest when a statement on their Web site announced the trip and castigated the play and gay people.
“You just have to wonder why they did it,” said Phelps-Roper, who on Thursday was in Topeka, where the family’s Westboro Baptist Church is located. “We’re going to picket a second-rate play, put on by a third-, fourth-rate college. What the heck?”
The Phelpses have become notorious in the U.S. for carrying provocative banners with the phrase “God Hates Fags.” They have picketed the funerals of U.S. servicemen who died in Iraq and Afghanistan because they believe their deaths were the result of the government’s tolerance of gays.
The ban probably will include any other members of Westboro Baptist Church. The church is monitored by the Anti-Defamation League and is classified as a hate group by the Southern Poverty Law Center.
