Here is the question in question.

At first glance this seems ok but on reflection it could be well disguised spam.

It is strange only their site won't work and every user who sees the question would need to visit the site (which works fine in 14.04 and firefox) to verify it.

I was going to leave it but based on a comment that seem suspicious of the question by @Bruni and seeing the down votes, should this be flagged?

What do you guys think?
