Your subscription list is hidden when you’re currently viewing a community or a user’s profile. It should be at the bottom of your sidebar on the right if you’re on https://lemmy.world/ or whatever instance your account belongs to when using the default desktop view.
You can also use something like https://old.lemmy.world/ and your subscriptions will be in the dropdown in the upper left under “my communities”. This can be viewed even when viewing another community/user’s profile.
Bots advertising crypto scam. If you look at the first comments they’re essentially all the same nonsense and just adding in random buzz words associated with crypto/ai.
