I suppose this might be a necessary evil when asking for product recommendations, but do we have an official policy on people suggesting products from companies that they work for (directly or indirectly)?
This answer is what prompted the question. Now, the answer is perfectly relevant to the question, so I wouldn't call it spam. However, the way the poster put up a photo for a competing product (which shows it doing exactly what I want) is a bit misleading. Also, the fact that he downloaded the image from the original web site, and re-uplaoded it to photo.se is a little odd.
I did a little more digging, and both of this user's two posts on the site are suggesting Lowepro products. Both suggestions are relevant to the question, and are done in a non-spammy manner, but the poster does not disclose any relation to the company.
Maybe I am just being paranoid? According to the user's profile, he works for a marketing company. Could this be part of their services?
To be fair, I really don't know if the user in this case is a shill for Lowepro. He might just be a satisfied customer, who messed up when posting the image.
