- It's on an old question.
- The user's name is
b2c, the same name as his website. That alone would be fine, but when combined with the others is... suggestive.
So I looked at his answer history. The chronologically oldest answer is fine but each and every other answer manages to work a link to one of his tools into it. In some answers, these references would be legitimately useful. Others seem much more naked and transparent. However, I don't know enough about the tools and some of the tech involved to be certain in some instances.
It appears to me that he seeks out older questions that could be answered by his tools and then suggests using them. This is shown by the fact that five out of six of his answers fit this pattern. They're old questions (relative to his answer), and they could (in theory) benefit from his tools.
I'm not entirely sure if this constitutes spamming, so I thought I'd bring it up here. Obviously I think it's spam, but what do you think?
