I don't see anything terrifying. Why are you and this twitter account posting something without an archive or screengrab? Was there something there? I don't know without evidence ...

That website is fucking terrible, but I'm saying that chiefly because of its flashing hideousness. Reminds me of the more noxious products of the Geocities era. You shouldn't be so cowardly about navigating the web. The content in question appears to be suggestive, but not pornographic. It's disturbing, but not illegal. What are you so afraid of that your skin was crawling? Are you sure you have the stomach to be investigating this? Don't work yourself up so much that you can't handle a verification step. Down that path lies being an easy mark for people spreading lies.

I can't link source tweet so supplied who made tweet and text of tweet with directions on what to do.
