Just looked into this a bit. While I don’t know exactly what each one corresponds to, I did find that pastebin has some lists of urls you can use.

This one has English and German-> the comments should differentiate what’s what. Hope this helps!

I know nothing about the arr stack, but the abbreviations and icons seem to just refer to the sites you’re supposed to put in (e.g. FX -> funxd.site, DX -> ddl-warez.cc). Presumably, because having those domains in the source code could be problematic for legal reasons and because they might change due to take-downs.

That also means you can’t just input alternatives. Those specific sites are the only ones that are supported.

Just look and figure it out. It’s really straightforward name matching. You don’t need someone to spell everything out to you, if you make a mistake just try something different. You can do it!

OPs_cops_post.html ass post. “Please explicitly tell me what illegal websites these initials refer to!” Guaranteed you are British 100% because only British cops would be stupid enough to do this.

Ddl is gonna be mainly stuff for poor Europeans who are scared of getting caught sharing files and are relying on the “loophole” of “I never actually shared the file, the file was shared with me and that’s substantively different” (it’s not, they’re just using it as an excuse to haul you in for some other reason or frame you for something).
