Hi Wagner.nardin, 

I think its possible to select every articles you want and then delete them, but I don't know how. 

In the manual I've linked, it's explain how you can build a front end interface with a delete button for every articles.

I don't think Seblod does batch stuff really, does it?

My thought would be in an afterstore field to loop through each item where $fields['delete_me']->form = 1 (a checkbox field) and delete 

Yes you can,

see this post:

use this code in a before render code in a search view and jgrid checkbox and a button submit.

Just test with article object. Should works with user object.
