If hobbyists want to exchange information about providers, use Protonmail. If someone sends you a pm on here, give them your Protonmail address and you will have end-to-end encryption, as long all parties are using the service. Plus, you can sign up anonymously. If everyone is not already using Signal Private Messenger for text messages, now is probably a good time to do so. Sharing providers information on here is not something I would feel comfortable doing. Addressing what a lady does or doesn't do along with her donation is not so smart. LE will probably be intercepting most everything on here, including pm's (which really aren't private)...
I'd recommend providers do the same...
Everyone want to maintain "discretion", but using gmail, yahoo, etc.. is hardly discreet. You may delete your emails, but Google doesn't (EVER) and they always comply with LE. LE is going to be on us like flies on shit because we all know that this has nothing to do with human trafficking, child prostitutes, etc...
Using a VPN may "hide" what sites you visit, but it doesn't encrypt your emails from any service (except Protonmail).
Stay safe...
