If per-user instance filters are implemented, perhaps instances could have “default blacklists” for new users for stuff like exploding-heads or lemmygrad that most people don’t want to see, with the option to manually un-block them if someone does want to see that.
Lemmygrad is blocked from federating with most other instances but still is a pretty large instance. Though that instance in particular is not very likely to look towards IPO.
It could happen if there was a very popular instance that didn’t federate with others.
Because lemmygrad is pretty huge and other instances don’t want their new users to be met with a flood of tankie content, most instances are blocking lemmygrad.
I don’t have a script to automatically subscribe to a list of communities on a new account yet, that’s a bit more difficult…
If someone wants karma they could host a modified instance where every post gets thousands of upvotes for free. Other instances can’t really verify whether that’s accurate.
