The connection to biggerpockets is already encrypted (note the https:// in the URL), and ironically, you're actually MORE susceptible to bad actors when using a VPN:  First, VPN providers are already pretty skeezy as a general rule, so why would you now want to route all your traffic through them?

I have No interest in buying any rentals and have never posted one post saying I do. only that I like to sell my rentals and be done with land lording :) but I get these unsolicited PM's and I report those as spam.And I hear what your saying this site most definitely has some bad actors on it.. past and present and will have in the future..

From then on, that lesson was....When I do anything that can have any legal consequences from any angle, before I act or sign, I ask myself what a judge would say.

"The market" (any market) to operate at maximum efficiency requires that all actors have complete access to information.
