Yes, I see what you mean, I think the Trending page should be filled with what the community thinks it's valuable. If they consider a post being of quality, they upvote it, if more are doing so, it reaches Trending. But the whole purpose of this platform is lost when people are using bots to get to Trending, 85% of the votes being bought.
As far as I noticed, the big projects don't use bots; they are reaching trending thanks to the support received from the community since they are doing something beneficial for everybody. But yeah, the bots need to set some more limits.
Flag-a-whale was a beautiful movement, and even if it had many people behind it, it's sad that the outcome was not the one desired.
I guess we have to wait and see what happens now. :)
