On April 23, a user on the Islamic State (ISIS)-operated Rocket.Chat server asked for suggestions on how to avoid surveillance. One user responded by recommending the use of a VPN, regularly changing "burner" phone numbers and temporary email addresses, as well as using encrypted email services and message apps, like Protonmail, Draugr, or XMPP-based apps.
A second user noted that Proton VPN is not safe, since it shares data with Swiss authorities and intelligence agencies. The first user then recommended Teleguard, noting that the original poster should carefully examine its user policy first.
