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.
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.
