I’m thinking about deploying my own instance where I’d be the only user and most probable I won’t have any communities.
The only thing there will be my account to interact with as many other instances as I want.
What would be de pros and cons of having my account like this?
Would it be harder to interact with other instances in some way?
When you follow a user or group, that is a request that the originating instance send messages from that group or user to your instance. However, if that group or user is banned from your instance, your instance will not accept the messages.
If the remote instance is blocked entirely, you won’t be able to fetch content from there at all in order to subscribe in the first place, and your messages won’t be forwarded along to that instance. A server block means that the two websites are no longer communicating with each other.
