How to remove your wikiHow account
Although there are numerous instructions on wikiHow about account removal, it will take much fuss to get rid of your account on the site itself, as can be read on https://www.wikihow.com/Close-Your-wikiHow-Account
Helpful Trick: Removing online data
Publicly visible text/images often aren’t properly removed even when you succeed in removing an account. Try editing or removing them manually before removing the account itself. If you’re unsure what happens to your tracks: this can be found mostly in the Terms of Service/Privacy Policy; otherwise you can always contact wikiHow and ask personally. By the way, removal requests don’t necessarily mean your data will actually be removed (e.g. due to legal obligations).
