I'm with ya on this one.
Yeah, the portal is cluttered with spam lately, and part of it has to do with stat-whoring, but a good chunk of the spam is put through by crews who vote 5 on everything they put up. Some of these crews have lot's of members, and even the shittiest flashes get through, some are even collabs with 10 users, strangely enough.
I watch these things, and sometimes I wish I hadn't and just want that lost minute or two of my life back, but watching shitty flashes just makes you appreciate the good ones that much more. One thing's for sure, I don't pull any fucking punches when I vote, if it deserves to get blammed, then I vote 0. Somewhere in the middle, I'll vote depending on how the flash affects me. As for real top tier stuff, well, you can pretty much guess at that one.
My way of fighting spam; working on a quality flash of my own. Been almost 2 months and I'm still in the early stages of production. I'm also learning flash as I go, so there'll probably be numerous revisions before I even think about putting it on the portal, not like some people who slap something together in an afternoon and hope for the best.
Keep fighting the good fight, I've got your back.
When it comes to flash crews, really only a few have enough power to heavily influence UJ flash (and could be outdone if enough Newgrounders voted fairly). However, crews can easily get certain awards (underdog and TOTW) by mass-voting/reviewing on their own flash and others' flash.
I remember watching the TOTW fights back when I was still active with flash. Lots of mass voting and AIM drama. And for what? It's stupid. I remember when random, unlucky souls got TOTW, and it was always fun to see what the bare minimum of Newgrounds currently was.
Nowadays, there are more people fighting for Turd than for Daily/Weekly awards. What the fuck is up with that?
Continue voting fairly, whistle stolen flash and abusive reviews whenever you come across them, help confused newbies understand the system, etc, and maybe we can get Newgrounds to kick ass again.
