I'm using the Boost app for Lemmy which has a one time fee to disable all ads. If you're sticking around it may be worth the investment if you're avoiding temptation.
Stay sober my dude.
Some app devs are setting up their own ad networks, injecting inline ads similar to how reddit operated. I know everyone needs to eat, but it's kinda lame when most lemmy instances the apps connect to are operated and funded purely by the generosity of random system admins.
