Google font name + *.otf, 99% of the time you can find it.
Add + GitHub to the end if all you get are paid links. - Such as helvetica neue *.otf github
Font activation has never worked on one of my illy pcs .. so when I'm editing something using an Adobe font and it won't download, that's usually what I do. Never had a font I couldn't find.
It's not really the most legal way to do it... But if you're only using fonts you have access to, you're not going to get in trouble.
[Edit] Seems a few people never knew this trick... So Github is a website that stores source code. And when people use the fonts on their application / web app... They include it in the source code. Technically they shouldn't be doing that... And legally you should still be paying for it. I've probably spent thousands on fonts, I only use this for ones I can no longer buy because theyre old, ones I cant find a pay link for... Or ones I already have, but they have a different naming scheme. For instance... Helvetica bold - We paid for it, but half the files we get are "Helvetica-bold" which doesnt work - we can manually change it, but its easier to find whatever basterdized font name someone else used, install it and never deal with it again.
