Wikipedian here (semi-retired), not on Steven's scale but I have written a little over 250 articles.

1. Such a user would be blocked almost immediately. If it were just straightforward vandalism you would report them to WP:AIV or WP:ANI (the latter for more complex situations) and they would be blocked. If they keep coming back with alternate accounts (sockpuppets) you can take them to WP:SPI and potentially get their IP range blocked from account creation.

   There are more subtly problematic users though, and dealing with them may involve arbitration and sanctions. I remember one guy in particular (not going to name names changed my mind, see below) who was mostly active on literature-related articles. He was an extremely knowledgeable and capable researcher but was also extremely opinionated and combative. He ended up getting banned for harassing other users and coordinating the harassment off-site. Hilariously enough he was unbanned years later on the condition that he was only allowed to edit a single article.

   There's a rogue's gallery of the more straightforward trolls who keep coming back if you're interested, (note that the names link to more detailed case studies) and there's also a list of the lamest editing conflicts between users.

2. This depends. The creation of individual articles is mostly solo, I would say, while improvement of articles is a group effort, especially if the plan is to steer it toward a featured article review. Getting an article to FA status is a big endeavor and usually takes a team of around half a dozen editors. Often you'll know a bunch of editors who are interested in the same subjects you are from running into them on other articles. If you were looking to get an article to FA you might go around to their user talk pages and drop feelers, or you might go to the talk page of a related WikiProject (For instance the WPVA) in order to get the attention of its members. The roles the individual editors take are ad-hoc and any coordination is hashed out on talk pages.

   For instance, when I was part of the team that was working the article on the German painter Caspar David Friedrich up to FA status my main goal was to hunt down high quality images from museum websites, to stub out redlinks in the article by translating the relevant articles on his individual paintings from the German Wikipedia, and to fill out a list of his works as much as possible.

   So while I was creating individual articles on my own in this example, like The Sea of Ice, The Stages of Life, and The Monk by the Sea, these were created as part of a larger, overarching project that was coordinated between a larger community.

Edit: Thanks for the platinum! Shout-outs to my old WPVA buddies - Ceoil, Modernist, Johnbod, JNW, Kafka Liz, Uyvsdi, and Victoriaearle!

Edit 2: You know what, fuck it, the user who got themselves banned for being an asshole was Ottava Rima. I'm calling him out because I just remembered he listed my article William Blake's Illustrations of On the Morning of Christ's Nativity on his userpage as an article he had written despite this single (not particularly helpful) sentence being his sole contribution to it. Fuck you Ottava.

Not really fair to use a single example to characterize Richter's work. He ranges from photorealism to painterly abstraction to geometric abstraction to any combination of the above.

PREVIOUSLY ON THE GIFT SHOP SKETCH...

Recently I've really been enjoying Battlecon: Devastation of Indines, a luckless game that simulates classic 2D fighting games like Street Fighter in board game form. It's all about deduction and reading your opponents intentions - unlike video game fighters, you don't have to have superhuman reflexes to play well. There are 30 different characters, each with unique styles. There are a variety of stages to play on, each of which alters the battle in some way. There are a variety of modes, including tag team battles that can be played multiplayer. You can play solo or co-operatively too, as there's also a dungeon crawl mode that basically turns the game into a side scrolling beat-em-up ala Double Dragon. There is an insane amount of content in the box, and play is incredibly deep and rewarding - yet for all this, you can play through a duel in half an hour or less. It has gorgeous art, too. seriously, I can't recommend this game enough.

Here are some reviews:
