Quite ironic how that Administrator even tells how you can avoid them. I honestly would suggest to hide them from logged in users and show them to anyone else? Quite frankly I think it puts people off to even use the sites if it is flooded with shady links. Especially new visitors.
Browsing this website is a pain in the ass on mobile. On desktop everything is hidden by using Adblock and Ghostery luckily.
Also if he needs more money to pay the servers why not make subscription for certain ranks so people can show their support? Say it gives you a different username, more inbox space etc etc.
