Try to avoid using services like twitter. The FSF is a little soft for twitter (in comparison to platforms like facebook or youtube) but this is not good enough reason to use it. You can try interact on the fediverse like diaspora and mastodon but eh. Be very suspicious of any websites that ask you to install software or run JS to function. I'd suggest using such sites in disposable VMs (qubes). You should take extra caution as you never know if a server is owned by or is now being operated by a glow in the dark.
