What they did
u/mihaipostelnicu, who runs a small web design and development studio and is also a university student, wanted to retire an email address they had used for years. They set up one Grok Bot assistant, called Account Cleaner, for that single job. It used the shared cloud computer and its saved logins to go through the services tied to the old address, change the login email where a site allowed it, and close the accounts they no longer needed. It was one of about 17 single-job bots the poster runs, all reading one shared context file about the poster and their rules. The poster's rule for this kind of bot is that deleting accounts or messaging other people needs their approval first.
How it went
The poster reports that it saved them from visiting dozens of websites by hand. They give no count of accounts moved or closed and does not say which sites failed. The job was costly: in the comments they say the first week, when bots were driving the computer to change emails and delete accounts, used up a full week of Grok Bot allowance in four days. Later weeks, with the bots mostly sorting mail and files, stayed under the limit.
Worth knowing
Driving a browser through many sites is the expensive kind of work on a shared weekly allowance, so expect a one-off cleanup like this to eat most of a week. Keep account deletion behind an approval step, since closing an account is hard to undo. Commenters raised a reported large cut to Grok Bot token allowances, which could make this costlier.
