I can understand your frustration, and I don't think you've been breaking any rules, so vehement slandering of your name is probably unnecessary, but I will say two things:

You've made a pretty substantial amount of money already, with very little effort. Some people are putting a lot of effort into writing quality stuff, while you've cornered the market on selecting other people's content to post here. Not that your selections aren't good (clearly they are, or no one would be voting for them), but given the effort:reward ratio, I'm not really sure why you're complaining.

More importantly, you're right in that it's not written anywhere that only original content can be posted - but just because we *can* post other people's content here doesn't mean we *should*. I've occasionally posted something from elsewhere on the internet because I think it's worthy of praise, but instead of spending all my time doing that, I prefer to focus my efforts on creating original, thoughtful, valuable content, because that's the kind of thing I want to see on Steemit.  Perhaps the message everyone is sending you here is that they want the same thing - because if everyone does things your way just because it's profitable, Steemit will cease to be original and just become another infinite loop of reposted content on the internet. In my opinion, we don't need another one of those.

The bottom line, and Steemit rule number one: **what's popular today might not be popular tomorrow**. So my suggestion is to focus on changing your strategy rather than complaining because it's fallen out of fashion.
