I think it would be great for KDE to accept donations through Liberapay.
Hi - just to double-check that you’ve already seen this: If your interest isn’t necessarily specific to Liberapay but in wanting or needing to use a method other than PayPal, there are several other donation options available by starting with links at this page: Donate and support KDE - KDE Community 
Yeah I’ve seen those. It’s mostly that I’m just not comfortable donating through the provided methods (eg PayPal Donorbox etc.).
Anecdotally, Liberapay has shown themselves to be rather ethical, imo, so I’ve taken a liking to donating through them. It would also be convenient for me personally as, by my experience, many other organizations and individuals have donations set up for Liberapay, so having KDE on there would keep all donations nicely grouped into one service rather than spread out over many.
I was just going to make a donation today and would like to second the call for more donation options. I feel like there are less options to donate than the last time I did so. Donorbox as was mentioned in this thread doesn’t even appear on the donate page (although I was looking for a one time option as well). My only options seem to be Paypal (ewwww), bank wire (which has additional fees) or Microsoft’s Github for an online donation. At least according to the donate page.
Somehow I convinced myself that Microsoft was the least bad option in this situation and chose to donate that way and simply remove the payment information immediately. Turns out once you give them your real name address, and payment information you can’t delete it without a support request. The whole process feels dirty at the moment.
Edit: Looks like donorbox is on the main page and not the other options page and it was ublock origin blocking it from loading. My apologies for claiming it was not there.
