@eii That's weird. Is it blocked by an antivirus or is it for blocks in your country?
In the first case you can just add an exception to your AV since it's safe. The major AV companies whitelisted it already but not all of them. In the second case you could try with a VPN or Tor Browser.

An alternative could be to use coinhive.com that offers a similar tool to mine monero (but it's a bit more difficult to mine).
Or you can just use their URL shortener for your links so that your visitors will mine for you for a few seconds before being redirected to your real link. Example and link to their URL shortener: https://cnhv.co/atuc2
