My credit card offers virtual credit card numbers AND the ability to auto-lock the virtual numbers so you can set a date and after that the number will not accept new charges.

I make sure to use a virtual card number for everything subscription based, then I immediately set the auto-lock feature to expire in a few days (give the initial charge time to clear but still plenty of time before the subscription would otherwise renew).

Some subscription services make it super tough to cancel. This method fixes that issue for the most part. Some subscription services terminate immediately once you cancel the subscription, even if you still have “time left” otherwise. This way you don’t really have to formally unsubscribe. It’s easy peasy pumpkin breezy as the common folk like to say.

When someone asks a thing like this on Lemmy, look up the same thread on Reddit (guaranteed to find it was recently also posted there) and copy-pasta some of the top posts. Guaranteed worthless internet up arrows.

I recently joined WTF and based on the list of the instances this place is federated with, my assumption is that’s the basis for the WTF name. So, maybe something like this could be useful for choosing an instance that’s not 1/2 filled with bat shit insane posts by default rather than requiring significant and immediate curation (i.e. blocking stupid shit like hexbear and ml).
