Before you install, Greasy Fork would like you to know that this script contains antifeatures, which are things there for the script author's benefit, rather than yours.
This script will inject ads on the sites you visit.
The author of this script explains:
𝗘𝗩𝗘𝗥𝗬 𝗔𝗗 𝗜𝗦 𝗥𝗘𝗠𝗢𝗩𝗘𝗗 𝗙𝗥𝗢𝗠 𝗚𝗔𝗠𝗘. ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ If you like the script, at the bottom of the settings, you have the option to restore & replace all ads with new ones that support the developer and all who helped him. ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ This script will not - and can't - inject ads into any website other than 'https://*.moomoo.io/', and for that site you'd have to manually choose to add ads yourself.
