Where do you find alternatives for your subreddits? I found most of them but for these I can't find any alternatives so I'm still using old.reddit and redreader.

Do a search in All for the keywords for the community name. Chances are you are either not going to find some of them or find multiple ones on several Lemmy instances. If you find several, subscribe to all and see which one is the most active, if you find none, consider starting one yourself.
