I think this was discussed in c/piracy - Lemmy can still get DMCAs, so people recommend obfuscating your links via base64 encoding if you'd like to post a link.
doubt it because lemmy is very obscure right now. Also that's how r/piracy got big in the first place.
The way social media (in this case lemmy) becoming big and maintaining it are 2 different things.. The strategy changes once you become big, but until then there should be no problem with being more helpful.
