This User seems to have named his account to promote his sideline SMB IT business (and his bio reads to me like a tout sheet/cover letter). It seems a bit gauche to me. Am I just too sensitive on this or does it go beyond the promotion guidelines?
The greater Stack Exchange community has agreed that such names are to be allowed.
The accepted answer on that one is what the SE policy is on this topic.
The identity you choose is a personal thing. If someone wanted to be called (for example) "Ubuntu Fanboi", we wouldn't be having this conversation. So is a username like "AskUbuntu.com" really all that different? It's not indiscriminate advertising... it's a username; and it's not a part of the information content of this site. In short, there is no "spam" to a username.
Personally I don't see any problem with the username. It's pretty clear that his name is in there, and a related company name. The name itself does not "promote" the company. If his username was "You should hire Acme Co" that'd be different.
His BIO is definitely within what's allowed. It's his place to brag about his accomplishments and undertakings. If those read out as a CV/Resume/Blatant pleading for employment, then so be it. There's no mandate in the general use of the site to ever see that.
I have not seen the content of his answers, but they would be of the most concern to me. If he is constantly promoting himself or his business then that situation is clearly addressed in the [FAQ]. If his answers have no mention of his business or available services then he's contributing to the community and that can't be wrong.
Just looked over several of their posts, no mention at all of the company or availability of employment. Looks like their on the up and up to me.
