Duplicated entry in radio-browser.info

[bluegeekgh]

The radio station "Ràdio Arrels" is duplicated in radio-browser.info (the incorrect is Radio Arrels without accentuation).
I've tried to remove the incorrect and duplicated entry but I can't find any option in the website.

we have to find an automatic way of doing this.
if the streams have the same endpoints, one should be removed.
