a collection of different methods of bypassing content filters
pro tip: to change the site in the bypass, just change https://anura.pro to https://whatever
also, data urls only fetch static html data. If you want to change the base64 (the random jumble of letters) to fetch something else, use the encoder file.
none of these can get past network-level filters, except for the proxy html, and thats only if the proxy is only blocket by something like a management extension, but not the network filter.
