Yes, some of it is from users being new. But really, these are classic signs of spam. It's pretty easy to spot once you get looking for it. I try to give people the benefit of the doubt, though. They have to have more than one of the above indicators for me to tag them. And honestly, if I tag a spammer, it may not do anything to change their behavior, but what it does do is alert others so they do not get rewarded for their behavior. Still, spam bots are commenting and curating and pulling from the reward pool just the same by sheer volume and timing. I guess it's an undertaking I feel is worthwhile. There are enough of us tackling it, hopefully a counterbalance on the ecosystem here will come in play.
