I try to control myself, so I don't become a digital account hoarder.
I don't want to fragment my online social presence too much, especially making potential “fans” (I doubt I have any) have to scatter around to find the content I produce. This anxiety isn't just about social media accounts, but digital services in general. Interesting combinations of website domain names, or the service itself, are enough to make me create an account, which in most cases I won't even use, or will use very little.
How I control myself: when I feel like creating an account on a service that I know I don't really need, I take the website URL and bookmark it in a folder in my browser just for that purpose. There are easily more than 70 websites there. And even so, I keep thinking about the service for a while, until this strange urge passes.
The upside is that if a service I use stops existing, I already have at least three others to replace it. 🤣
