In the past imgbb was used to post CSAM to some communities so some instances remove links to images hosted on it (or I guess ban the user in the instance you were on)
Edit: seems like that was lemmy.world, reach out to their community team and ask to be unbanned if you want your account unbanned, seems like they did that for someone else in the past
So in this if you tap the title you go to the post on gamedev since its the oldest post. But if you tap game_design at the bottom you go to the post on game_design
no, theyre still two different posts and have different post views outside of the feed. Just one is more prominently shown in the feed while the rest are just links in the cross-posted to section below the post in the feed when it detects that multiple posts have the same url. Comment threads combining would be a separate feature
yeah ill probably have to make an issue on all of their repositories
its pretty much only supported by the main instance web frontends (lemmy-ui and pangora-ui) (been supported on lemmy-ui since before all of the apps were made)
currently recommended in programming.dev to cross post to as many communities as you can to give content to the lower activity communities and since there tends to be a lot of overlap with topics but thats conflicting with current app behaviours
Havent done a check on all of them yet but figure they should all match the behaviour of the main lemmy frontend and its better behaviour to have then to just let it flood
So far I made this post here and opened up an issue in the jerboa repository since those were the two that were reported
