Reddit Migration

You do you, personally, I don't want to give that site any more traffic

A lot of good options above. I have only viewed r/modcoord to give my 2 cents and do my sub's blackout polls. I did it via Apollo instead of desktop, didn't know any other way to show support.

Every time people migrate between platforms there's going to be a period of adaptation, where the massive backlog of knowledge left behind is still useful and necessary.
The best solution to this truly is to use it as needed as you migrate over, but you should also bring in any new questions and subjects that you may have, because that's the only way to start rebuilding that information network somewhere else, y'know?

You can but you'll need a permission note from your mom. Seriously it's not a big deal, you can use both at the same time, nothing says you have to quit cold turkey. It would be more beneficial though i think to link discussions to the Fediverse rather than just to Reddit.

Instead of just tweeting, toot to the Fediverse as well. Try not to be annoying about it demanding people use the Fediverse, just do it the quiet sneaky way. Get people clicking Fediverse links with topics they would be interested in, and with their own volition they will learn about the Fediverse and come to look at it as a viable choice, hopefully.

Why not? Consume without contributing.

Run ad blockers.

Not well-versed with mobile solutions. Maybe use something like Brave with built-in blockers. Or run reddit through something like Hermit App which also has blockers.
