@masukomi In theory, there's nothing wrong with that approach, and some systems do prefer similar options even in places where tools like this are more easily available. But that approach comes with its own drawbacks; not being able to collectively follow people or be followed, having to manage login data for dozens to hundreds of accounts for larger systems like us, and no matter how streamlined you make the process, at least some level of "navigation overhead" to switching between members, among others.

Ideally, the best solution lies somewhere between the two, with quality built-in support for both multiple accounts and "multiplexed" accounts, so systems can use either or both to suit their needs. But practically speaking, even though there's far more systems out there than most people think, we're too small of a demographic to make that investment seem worth it to companies; the most effective solutions for our needs will likely always come from creative systems making things they themselves want to use.
