Expected scenario after deleting account / plugin

Hello,

First of all, I would like to say this plugin is a very interesting initiative. Keep up the good work!

I’ve been trying to test it yesterday on a clean install of WordPress, but unfortunately run into some issues mentioned in other places. I’m still investigating, however my Site Health page shows that “Your WebFinger endpoint does not return valid JSON”. Which was not true (?), as I was able to see the content under the provided link. So I decided to continue the test and saw that my account indeed can be searched in Mastodon.

1. Then I created another admin account and deleted the old one. However, the old account never disappeared in the search in Mastodon. Is it a bug, or anything I create will stay there like this? I’m a bit afraid of testing further, as I don’t want to leave a trace of garbage under my domain in the search results.
2. I tried to deactivate the plugin in hope this will solve the issue, probably making the whole server disappear. However, the account was still visible in the search. The only thing that changed, was a list of followed accounts on my private account – the test account disappeared there and the number updated correctly. What is really an expected scenario in a case of deactivating the plugin? Will Fediverse account just disappear and people following it will need to follow it again?

I’m a bit new to the concept of Fediverse, so please bear with me.
