I disclose upfront that I have not gone to the link.
However, I am up on the newer science that is very much against ECT. If the site really demeans those who are "for" it well, that's not good.
If DocJohn says he will check the link (as he implied for the thanks for the note) then he will...and if it isn't removed then generally that means he thinks we can handle the information (though sometimes other things interfere and admin don't get to the complaints as fast as a member demands.)
Try to let it go. Don't take it personally, neither the site/link nor that it's still on site.

You went, you read, you complained. Task done.
