I guess there are ways to prevent such outcome by pre-selecting subscribers by level of technical knowledge on the subject.

An online test (chat like) is applied also by private torrent trackers to select uploaders also by tech knowledge of the subject before they are accepted. The same system can be extended.

Unfortunately, this is possible only where are many wanna-be subscribers to choose from the pool.

It’s sad that people are trying to improve things only by fear and not be reason :(

Hello.

Have you tried an FOSS XMPP server solution ?

Hello.

Hopefully, feedback is appreciated.

Searched on Google Play with no results, same on F Droid.

Thanks.
