I keep getting this message for any webtease that runs on script and isn't just a basic text adventure

Nothing is blocked for me. I opened several EOS teases with no trouble.
Perhaps it's because of where you are located? Have you tried using a VPN to change your location?

try a different web browser

Try a different browser
Check your antivirus settings - temporarily disable it to check if that is blocking it
Disable any userscripts if you are using tampermonkey / greasemonkey / violentmonkey

I've definitely seen this before and it wasn't anything milovana had changed
It has usually been one of the above
I think the last time it happened it was an overly aggressive antivirus product that decided that the javascript from eos teases was dangerous so blocked it.
I have a vague recollection of trying to fix it in the antivirus settings but ended up switching to a different antivirus product - it might've been bitdefender that was the problem one but it was at least 5 years ago so can't be sure and it may be better now

Had this in the past. I suspect it was a browser extension. Incognito tab worked as usual.
