How is an embed spamming my blog?

I think this site is preparing a spaming system, not fully working yet, so I’d like nobody mention its name, if you actually find out how to help me.

One of my site’s pages, https://socialblogsitewebdesign.com/cultura-y-media-5-en-buenos-aires is throwing an error (many, since I’m doing changes) about a GET call and the page is not found, but I wonder how it is trying to load a page without interaction.

I though one of the limitations of flash was exactly that: that it wouldn’t actually load a thing until someone clicks it.

I know it comes from it, because I removed it and the error goes away. The page trying to load is https://www.twitch.tv/discovery/game?name=null
