To expand on

Andre was pointing towards bit of a special feature in a post he made last week to check out the profile of a room peer without puffing up your own local DB.

...another solution is that when you open this anonymous account, a prompt shows on your SSB app saying “do you want to temporarily view this account’s content?”. If you press yes, it performs replication of that feed (possible because you’re directly connected to them, so no gossip), but stores the replicated content in /tmp or something, and let’s you view their content. If you don’t follow them, the content would be automatically deleted later.

That idea is not implemented yet though
