Hello my friend,

Accessing unknown links is always dangerous. In the situation where you live, by clicking on the link, you have authorized someone else. These authorizations may include message authorization, wallet authorization and other different authorizations.

Click on the key icon that says 'Steem Account Authorities' from Steemworld.

If the authorized names appear in the 'Posting Authorities' section of the page that opens, cancel them by pressing the cross. Then click 'save changes' to save the changes.

If there are similar authorizations in the following sections, you can cancel them in the same way.
