I am also curious about what is web mining script,as I search on internet, this is the meaning that I found. A crypto mining script is a function that is placed on a website, and makes use of a website visitor’s central processing unit (CPU) to mine cryptocurrency. Those operating the script are rewarded with cryptocurrency when a block is validated. Mining starts as soon as a user accesses a website running a crypto mining script, there is no need to infect a user’s computer, or to exploit any vulnerabilities, all that is required for mining is that a browser have JavaScript activated. Because crypto mining scripts utilizes a user’s CPU, a machine’s overall performance is likely to slow down as a result of being on a website that uses these scripts.

This is the first time I encounter that kind of script, it's the evidence how advance technology needed of crypto community by using other resources. For "DronICO" , do you have evidence?
