Hi there, I would like to provide some context.
html-load.com, html-load.cc, content-loader.com, as well as other various domains are owned by an Anti Ad-Block service called Ad-Shield.
How they work is when a website attempts to load ads and fails, Ad-Shield kicks in and attempts to "recover" it by loading in advertisements via the domains above.
However, when it fails, it will put up the anti ad-block warning.
I do not like how deceptive their practices are, as these domains "sound" important but they are used solely to "restore" ads.
Plus, they do not make it clear that they are an anti ad-block wall and that it's by Ad Shield
Instead, they simply tell you that you need to whitelist their "important" domain.
In their blog, they basically admit they don't care about your network policies. As they say that most ad-blocker users are "unaware" because IT deployed it, and that users are actually fine with and dont mind ads. Directly going against the wishes of the IT Administrator by loading back in ads using their domains.
