I do suggest people get secure and free email account on proton.me and share those with your friends, so that you can keep in touch even if the various sites go down. The content in emails sent between proton.me accounts can supposedly (security experts say it can’t but I have not personally confirmed it) not be read by even proton.me, so that adds a level of security you won’t find with say gmail or others. Meta data and the subject can still be read though. It is just a way to stay in touch in case shit hits the fan a bit too much.
I also don’t know how much longer one can expect to be able to host clear net sites that deal in some of these subject matters. It may be good to get some TOR/.onion and I2P sites set up, hosted by people more directly, instead of data centers that don’t want to host this kind of stuff.
Also maybe some coding needs to be done to make a server software that stores encrypted data that only can be decrypted by those with keys, so the only thing the server would know is who stored what block of data and how much, and all blocks are say 1MB in size, and larger files consist of several blocks, and decryption happens on the client layer, in the browser. I have plans to make something like that eventually. Sadly I don’t function for coding every day, so it is a little difficult.
I still see the account suspended when I go to the bookmarked forum links, like I saw before, so I am not overly worried yet, I have seen this before. Though it is a bit odd that other site(s) got hit at the same time.
