In the real world, Joshua Alayon worked as a real estate agent in Pompano Beach, Fla., where he used the handle “SouthFloridasFavoriteRealtor” to urge buyers on Facebook to move to “the most beautiful State.”

But online, data revealed by the massive hack of Epik, an Internet-services company popular with the far right, signaled a darker side. Alayon’s name and personal details were found on invoices suggesting he had once paid for websites with names such as racisminc.com, whitesencyclopedia.com, christiansagainstisrael.com and theholocaustisfake.com…

After Alayon’s name appeared in the breached data, his brokerage, Travers Miran Realty, dropped him as an agent, as first reported by the real estate news site Inman. The brokerage’s owner, Rick Rapp, told The Washington Post that he didn’t “want to be involved with anyone with thoughts or motives like that.”

Alayon told The Post that he does not own the ‘racisminc,’ Holocaust-denial or other Web addresses but declined to say if he had owned them in the past; the records were hacked earlier this year. But in a screenshot of his Epik account, which he sent to The Post, the information for four other domains he currently owns matches the private records that can be found in the Epik breach.
