"These individuals have been permanently banned from using Airbnb. We have a number of technological tools we use that prevent individuals who have been banned from our community from using Airbnb in the future," Airbnb spokesperson Nick Papas tells Business Insider.
Papas pointed us to an Airbnb blog post published last month that discussed some of these tech tools.
"Fraudulent actors often exhibit repetitive patterns. As we recognize these patterns, we can apply heuristics to predict when they are about to occur again, and help stop them," the post explains.
In other words, Airbnb is using sophisticated algorithms, known these days as "machine learning" to monitor its system. If these squatters attempt to fire up new accounts, they'll be found and kicked out, the company promises.
