Maybe because the PAL community is so diverse, with diverse interests... it could be seen as a microcosm of Steem.
But with the more niche tribes like sports, steem-monsters, etc... well, they are more nuanced and specific. It'll be obvious who the spammers-n-scammers are, and I believe part of the functionalities of these SCOT/steem-engine tribes is that there is a way of muting 'offenders'.
Maybe that functionality hasn't been dropped into palnet yet?
This is an issue I'm trying to wrap my head around, as a community I am part of would love to get a 'tribe' project up and running, and take it out to the world of our niche... but its the opportunists I'm worried about who will ruin it for any newcomers to the site.
As for my content, I honestly write for my own enjoyment. For some reason, I get more authentic, organic audience on Steem than anywhere else. I guess its how I've found myself in the community I was talking about... "found my audience" you might say.
And I get a wee bit of imaginary money for it at the same time. I've got a well-paying job I love, so I'm certainly not doing this to buy a Lambo ;-) LOL.
