TJ - I used to do both but bagged WarmShowers after a difficult encounter with the website owner.
A guy was coming thru and when I Googled him there were news articles reporting
he had pled a lesser charge involving sexual assault during a fraternity hazing.
When I contacted the website owner and questioned whether this guy should be using WarmShowers.
the owner said it was the responsibiity of the host to check up on any guests.
That WarmShowers wasn't in the vetting business.
I found his response absolutely unacceptable and dropped out.
