Let's start with the OP.
Each elf has things he pays more attention to than others, and I think I'm the one most invested in checking on quality of new submissions; I especially watch the mountains, areas, routes, and canyons, and trip reports to a lesser extent. I pay virtually no attention to the other page types unless someone calls attention to them.
However, sometimes I miss something or see an incomplete page go up and forget to check up on it a couple days later. That's why it's helpful for members to point out bad pages.
I agree it's better for members to attempt to help rather than just ignore the bad stuff or wait for the elves to nuke away. More than one solid SP member started out as a shaky one who got some good help from seasoned members. For me, it was the much-respected, much-missed SaintGrizzly who stepped in and helped me out.
After seeing this thread yesterday, I was going to delete submission #1, but now that the author has logged back in, added a map, and pledged to improve the page soon, let's give the benefit of the doubt and wait.
As far as submissions 2 and 3 go, I can't see too much of an issue there. It's disappointing that the author copied so much text from another site, but he did at least credit the site rather than try to pass off plagiarism. And it's disappointing that he hasn't worked to display the pictures in the text on the main pages, but given the presence of pictures in the gallery and the attached route pages, all the necessary info is there and the pages fall under the guidelines of what a complete page is.
Could the pages be better? Yes. Are they deficient? No. Maybe it would be worth trying to work with the member to put more into the pages. On the other hand, keep in mind that maybe one can only do so much with peaks that are bushwhack routes to heavily forested summits; these are not alpine skyscrapers we're talking about, so opportunities to wax poetic about the beauty of the route or make us drool over stunning pictures may be extremely limited.
As I've said before, I sometimes worry that the proliferation of pages that go way beyond the tools SP provides seem to set a standard that is at once too high for most and perhaps intimidating to new members. It's great that some people put so much work into their pages, but let's not give the impression that every page needs to be a work of art.
I'm not insensitive to the concerns-- there are some pages on SP that went up just days before I climbed those peaks, and I was disappointed to see the pages fall far short of what I would have done with them, but in all cases, the pages were still sufficient, so I found other ways to communicate my knowledge and passion for those peaks. This meant route pages, trip reports, and photographs with informative captions.
Now the other issue.
Spammers and scammers often use undersized profile photos, and often of women, in order to appear more legit, and the better ones will put sneaky little links into seemingly legit posts, so I could understand an initial impression that this account is a phony one. However, nothing else about the account or the post, and this includes the email address and IP address, suggest anything false. If I end up wrong about that, so be it, but for now, I think that person may deserve an apology and a removal of the snarky post.
And Fred has a point about comments, and I'm not singling out lcarreau here. A number of times, I've seen and deleted inappropriate comments (on photos) made by strangers to female members about their looks and their bodies. It may seem harmless since it's between strangers over the Internet, but we ought to be more careful about what we post and how people may perceive it. While I am sure some members may appreciate such comments, I happen to know that some don't, and for them, it makes SP an unwelcoming place when all they wanted was to share and receive information about mountains.
We all like a pretty face, and it's not surprising or bad that attractive women seem to garner more votes and "Welcome!" comments to their profile pictures, but we should still keep in mind what's appropriate and what's not. So I'd have to say that the post about this new member, unless there was a valid belief that the person might be a spammer, wasn't a good idea.
