How to remove your Plazilla account 
Plazilla is open en duidelijk over accountverwijdering, zie de directe verwijderlink. Al je gegevens zullen verwijderd worden (ook je mogelijke inkomstenbron, dus).

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 Plazilla and ask personally. By the way, removal requests don’t necessarily mean your data will actually be removed (e.g. due to legal obligations).
