Hey Bin, thanks for pointing out TOS. Here is my piece about helping out: https://medium.com/technical-excellence/help-a-fellow-writer-one-way-keep-your-tabs-open-2bdef6b73449

But let me highlight what I wrote as well: "Finally, I am not in any way suggesting that readers mobilize an indiscriminate effort. This is not a call for practices like clap and run. On the contrary, I think that helping the articles that piques our interest get a chance in the spotlight is the right thing to do. Especially the shorter ones. My notion is genuine all the way. I encourage readers to leave genuine comments, share articles on social media, and engage with writers in meaningful ways."
