I was wondering whether that could cause issues for the limited servers available, like when the mass migration from reddit happened.
I know one account sounds like nothing but as a general practice would it be bad to add more accounts that would be mostly dormant?
And if one does create a throwaway would it be better to delete the account afterwards or leave it be?
To add to what others have said, the real source of load is browsing. It’s much better than a few months ago, but it is still the case that users actively on the web frontend is the biggest load.
If you are actively using a single digit number of accounts simultaneously, no issue. A bot farm using 100,000 users simultaneously is a big problem.
