edit september 2020: i wrote this when i didn't know much about the account, but now that i do and also have the top search result heres pretty much the proper explanation. in the EU we have this pretty neat thing called GDPR which allows us to request data removal from companies. scratch also has to obey this, and so they have a system in place to wipe accounts. gdpr0000001 was likely a test account, however the accounts after it (gdpr0000002 03 04 etc) are likely real people who've requested their data deleted. the reason you can't follow them (massive simplification alert) is that the APIs don't properly provide the page with the correct data to know who to follow, and so the page doesn't load correctly original text: okay, so theres this user named gdpr0000001 who joined scratch before it was created, surely the scratch team should've done something about them??? seems like it may have been a scratch team account based on how broken it's page is and you can't even follow them easily. also they have got a location not given which is pretty cool if you ask me. edit: world_languages has a way better explanation. it's an account that most likely was removed due to GDPR laws. (although i guess 01 would have been a test account for this and the ones like 02 03 04 must have been new)
