Hilico that was either a LOL or you..........................nah, you can't be serious

It is a contentious issue. Sometimes the site is innocuous, sometimes mildly commercial and sometimes very commercial. For this reason PPRuNe HQ made the rule that there would no links to any site that had any commercial offers. Those sites that are of interest only are welcome.
The reason is actually easy to understand. All the ads you see around the site are paid for. Given just that, it would be unfair to allow any links to sites that are commercial and do not pay to advertise.
However, when you need a question answering, say "e-mail answers ONLY."
Hope that explains the reasoning.
