Got this message: "We have detected that an extension you have installed may be violating the Fair Play policy and you will not be allowed to play until it is completely removed."

Console.log:

How did they detect ? Load: chrome-extension://extension_id/img/icon.png

n.src = "chrome-extension://" + e + "/img/icon.png",
            n.onload = function() {
                t(!0)
            }
            ,
            n.onerror = function(e) {
                t("chrome-extension://invalid/" === e.path[0].currentSrc)
            }

Differences:

Denying load of chrome-extension://dokkeahnmkbkoijcglpddnkjeipgepcm/img/icon.png. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.
icon.png:1 GET chrome-extension://lohcfjmdomblangndimbjfecoapohjlb/img/icon.png net::ERR_FAILED
icon.png:1 GET chrome-extension://aobaabcegagilfeibfeifjpahgefklon/img/icon.png net::ERR_FAILED
icon.png:1 GET chrome-extension://ekllijndikebdmfpaeegkjjdpjpliahf/img/icon.png net::ERR_FAILED

Workarounds:

• unset window.chrome and window.chrome.webstore (partial workarounds, won't work later)

isChrome: function() {
            return !(!o["default"].chrome || !o["default"].chrome.webstore)
        },

• use developer mode to load the extension
• block the script (won't work, tried to do it with ads block)

Solution might be

• conceal us by crafting a not found message from any request to our extension (instead of depends on chrome error, which revealed us) https://developer.chrome.com/extensions/webRequest (take a long time)

Thanks to your work!

Finally, I fix it.
