I'm not necessarily a fan of big blacklists (which is not to say I'm against them: I'm ambivalent about them, and if someone wants to use a community blacklist I'm not going to give them grief for doing so), but I do think that you should consider who you're supporting when you offer incentives.

I don't think Partiko's bad. My leaving Partiko isn't a moral stance against Partiko potentially creating issues on the blockchain, it's that I hate ads. I'm just adding it as a concern, something that Steempeak doesn't have a problem with because they're not supporting people with upvotes just for making content.
