That's fine. It's a completely optional feature.
> "Reddit incentivized good comments without ETH"
First of all Reddit comments are garbage. Second, Reddit only allows you to gift another user "Reddit gold" if you really like their comment. Your "gift" to the recipient is just paying Reddit, and the recipient doesn't get any of that money. In Zsync, you can directly tip the user whatever token you want, and no platform or middleman is getting any cut (ie. I make no money here). I guess theoretically this could be accomplished without crypto, but I'm guessing not every user wants to link their bank account with a social media site, nor do I want to deal with that headache of brokering international bank transfers.
I agree on the need to filter out out abuse and spam.
Thanks for your feedback.
