"You give us the addresses you want to monitor and for like a buck a month we'll tell you if somebody is hosting an Airbnb or another site," Teman told PIX11 News.
In 2014, Teman said he rented his Chelsea apartment on Airbnb. He thought a couple would stay in his apartment, but instead a promoter hosted a paid orgy in his home.
Teman was evicted -- and more.
"I ended up on this housing court blacklist," he said.
With his new website, Teman hopes to bust illegal activity on Airbnb and protect others from ending up in his situation.
"We can tell landlords, we can tell law enforcement where these bad actors are. Airbnb tries to give the impression that it's a bunch of people just trying to get by, but it's mostly professional operators that are driving the business," he said.
Airbnb did not respond to PIX11 News' request for a comment for this story.

The renovation, she said, cost three times the original estimate and took seven months, instead of the 45 days the contractor promised. âI used seven years of savings,â she said. âIt will take me a few years to see the investment back but itâs worth it.
