Perfectly alive with aprox 100k daily users

I compile the source code: git clone, cd mldonkey, ./configure, make, make install

You still have realvnc lite. It is free, 1 user, 3 machines, less features, but the basics still there.

You could use i2p for torrent it is free and secure, but slow

It’s just Germany, the rest of Europe (EU and non-EU) doesn’t actively care about them unless it’s cp.

It’s still my favorite network (using it from more 20 years ago), but for the latest things I use bittorrent and seed to both networks (bittorrent and ed2k/kad) through mldonkey 24/7.

Well you could run these services in your server (only if you have enough spare bandwidth, ram and cpu) to help the comunity to circumvent censorship in some countries, like Russia or Iran. Here you have more information for tor and i2pd.

Tor relay (guard/middle or bridge/snowflake) and i2p node (i2p, i2p+ or i2pd)

You could seed on ed2k/kad networks, just share the folder

eMule works just fine nowadays with fiber connections.

Maybe you could try ed2k/kad (emule/amule/mldonkey), soulseek or dc++ networks. Just drop the files in the sharing folders and seed. My preference is ed2k/kad.

You could try on ed2k/kad network (emule/amule/mldonkey)

I just use jerboa

eMule/aMule/Mldonkey works like old limewire, it is from the same age, but still kicking

You can still use ed2k/kad network, it works fine.

Tor bridge/relay and i2p node

Snowflake and i2pd could work but not in the best conditions.

Snowflake/bridge is used when you do not want the authorities/ISP know, you are using tor or because it might be blocked (like on contries with censorship). When you are running snowflake/bridge you are helping these users. For the contrary, if you use a normal tor relay, they(ISP, authorities, who ever is watching your connection) know, but they do not know what you are doing.

A tor guard/middle relay or bridge/snowflake and i2pd node.
