/wallstreetbets is a rabbit hole. Apparently some "high-profile" reddit subreddits are trademarked. The list includes: ELI5, TIL, ShowerThoughts, IAMA, AmITheAsshole and others

That rabbit hole will lead you to intersting post by original wsb reddit founder on reddit here:

In short, founder tried to trademark the wallstreetbets name, but court gave the rights to reddit instead (infrastructure owners or something). Looks like when the subreddit "brand" starts to get huge and influential, reddit will want to make sure that it exist exclusively on their platform?

There is no official list, but it looks like one can be sure that when they try to trademark their subreddit name in order to move out of reddit, they will not be able to do that. Officialy they only say this: https://redditinc.com/policies/trademark-use-policy - this includes things like r/, logos, and subreddit like /AMA

But wsb founder Rogozinski says in his post that reddit trademarked more subreddit names. The list includes names like ShowerThoughts, TIL, ELI5 etc. You can check for yourself on US patent platform https://tmsearch.uspto.gov by searching these communities names in trademark search. They're in fact there.

And now what does that mean in the context of Digg? I mean Digg cant use the same names to make money right? As long as Digg's future is still uncertain - one scanerio is obviously digg is going to fail - reddit doesnt care. But if Digg catches up and people start using it, then Digg can't use these communities names, if they are for profit company, correct? Unless they make a deal with reddit?

I guess this might is our mysterious "high-profile" digg cummunities list, founders of which might be in danger?
