I recently was reviewing some old messages and linking to some of the guest accounts, in particular those who had stayed over a year or more ago and had caused problems in the home. Mainly since I was curious if the problem had persisted and what I found was interesting.
90% of the really bad guests had no further reviews after mine (which had been negative). There were two guests who no longer had accounts. One of those had been a homeless woman staying with me nearly two years ago and I had checked her account before and had seen numerous other negative reviews about her drug use, how she had destroyed rooms, and had smoked in houses with no smoking rules. What makes that particularly interesting is I am almost positive I received an instant booking request recently from a no-review account, established last month, that was her. The account had knowledge of the house specific to her stay and signed under her name, which was different from the account name which appeared to be a type of handle (see had used "Princess" before under her old account, which was not her real name).
This brings up an interesting question. Does AirBNB simply allow horrible guests with bad reviews to just start up new accounts? Are there no safe guards to make sure a 2-3 star guest, who had caused major issues in residences, is not simply starting over with a clean account? I wonder, with that said, how many of those other 90%, with no reviews after mine, simply started up a new account because I gave them a bad review.
