Hello. Sometimes user accidentally add wrong link to YouTube video. Users add “search results” link:
https://www.youtube.com/results?search_query=%D0%A1%D0%B5%D0%BA%D1%81%D0%B8+%D1%8F%D0%BF%D0%BE%D0%BD%D0%BE%D1%87%D0%BA%D0%B0

And system allow to add it to ES site.

I suppose ES should display message and do not add this link type.

Thanks.
