Some people have a weird habit of creating a throwaway account for every comment they make, no matter how mundane. I’m not sure what the rationale is, something privacy-ish i guess?
I like destroying accounts from time to time. Prevents becoming attached, identifying you with your comments, flushes your permanent record, etc.
Besides, it’s a pain in the ass and you might get banned so you end up working fewer hours for the website.
People with careers are getting cancelled because of their opinions published online. Nudging people to identify themselves online is inviting them to dig a grave
