Error: It is not checked only by URL.

We check for names. And combine with alternative words ...!

Why do we do that?

Because a poducto can have more than one URL. Example: mobile applications can have the url of the application store and also the url of the official website.
Therefore you should check by name, and some relevant words.
to be able to observe the list of existing matches in the Steemhunt database.

That check by name, is done in a text box located next to your profile picture in the main interface of SH.

These are my tips, so we check the moderators .. Have a good day. Greetings.
And I am not sir. LOL...
