Maybe all of the providers were assisted by one person.... and that one person ran into some sort of trouble.
Maybe that assistant's parents or kids found out, their S.O. put their foot down, they found out they are pregnant, they are in the middle of a nasty custody dispute, they got busted for something prostitution related, they got busted for something completely unrelated, they are dealing with major health issues, they got in a car accident, they are going to rehab, they found Jesus, they [fill in your own scenario].
The community loves to speculate, and that speculation always takes the tone of "OMG THE SKY IS FALLING!!!"
I assure you, the sky is not falling. A week from today, everyone will be carrying on as usual and this gossip fodder will be a distant memory, as we move on to the next "OMG THE SKY IS FALLING!!!" situation.
I've been doing this, on the internet, every day of my life since 1997. This is nothing new, or even all that interesting. People often leave this business suddenly, it's really not a big deal.
When I worked the casinos in Las Vegas (circa: 1998-99) we went to jail every week or two. I'm sure that independent providers who screen and handle their business in a more discreet manner run into trouble far less often, but Clark County jail is still there waiting for them. It is a part of being in this industry, unfortunately.
Conduct your activity in this industry with caution, don't take unnecessary risks, and if paranoia is eating you alive..... it might be best to consider a different hobby. Stamp collecting is way less nerve racking!
Hang in there, this too shall pass.
Always,
