Grindr guests are personal guests, not customers of a service like Airbnb guests. As another person stated, the Airbnb guest is likely to be unsupervised, and has no vested interest in keeping the house and local community nice other than general decency and their Airbnb reputation. This is enough for many visitors, but there are a portion that don't care.

Are you willing to admit that this may change the local community dynamics in a negative way for long term residents?

I use Airbnb. I think it's great (from my perspective). However, I understand why some may want to limit it.
