I have this black bar too.

What does it say? on jerboa is states that i use unknown mobile client, with infinity, android client. All i have is adaway on my phone

I think bots are too agressive posting everywhere. example linkbot, it has posted over 20000 posts and its only one month old account.

After i visit community on another instance and it shows up searching from my instance, do i or someone else on my instace need to join on that community for it to show on my all communities feed?
