I have noticed recently that if I run a sale on itch for a paid project I get a spike in traffic from Russian and Chinese websites that link to games that go on sale for free. I guess it is nice that somebody is playing my games in those times, but I have also never gotten a tip.

I am curious on what other developers' thoughts are on these sites? Are they harmful? I worry a bit about where the downloads end up, as far as being repackaged or whatever.
