I've been stumbling upon more and more users which fulfill all of these points:
- 1 Rep
- Company website as homepage in their profile
- Linking/suggesting a product from this company
- Less than 10 answers and all about their product
So, I've learned from Michael (not you Mrozek ;) ) that this isn't necessarily a bad thing. They're complying with the FAQ since they're stating their affiliation with the advertised company/product. But, they've failed in my opinion to give something back to the community (hence the 1-Rep).
The FAQ does include this sentence:
Also, if a huge percentage of your posts include a mention of your product, you're clearly here for the wrong reasons.
Now that adds something new to the mix; all of Michael's answers were about his products, but they were useful, so it was decided to keep it. If such a user is useful, I agree, we should warn him maybe, but let him be. But what to do with those 1-Rep users which vanish (read: stop posting answers) after 1 to 5 answers of advertisement?
