A little bit of background first: Over on Puzzling.SE, we've been nuking users that look very spammy, before they've had a chance to post anything. It began with posts like this, which advertised watching things online and stuff.
So then we (I'm not a mod there, I just pinged them with links) started nuking users with spammy profiles before they had a chance to post. Like this 3D Printing user. They have keywords that might show up in a Google search and a link to their site.
Then the line gets a bit blurrier with profiles like this. The entire profile looks like an ad for the product, and they have no positive participation. The profile is still something I'd flag on the spot as spam.
...but now, after a whole long conversation in the Teacher's Lounge (link will only work for mods), it turns out that apparently we (me, the Puzzling mods, and apparently doppelgreener) are in the minority here. That most mods will not nuke a user based on that, and will wait for them to actually post spam, the concern being that a legit user will be thrown under the bus - with this person being an example of someone who might suffer from being nuked unfairly. (My opinion is that if they look like a spammer, they should expect to be treated like a spammer, and that if they want to be a positive participant they should create a less suspicious account.)
So... to resolve this (the conversation took over two hours), is there any official policy or anything on this?
Note: I'm aware of the Rules for Profiles. This is different, specifically as 1.) This is about the rules for nuking an account, and 2.) This has caused a lot of debate in the past couple hours and I feel it's time for a new discussion on this.
