To be honest, personally, I see posts like these as the on-line equivalent of marketing and survey phone calls – a bit of a nuisance and I would not answer questions over the phone about my lifestyle and hobbies so why should I on line via an untrusted source/link?. As you are from Germany, you may be unaware of UK spam/marketing rules. You would be better posting your questions here, on the forum, and collating the information from the replies. That way, it provides a healthy (rather than sarcastic) discussion whereby the forum benefits too, and individuals who participate won’t be bothered by spam emails (you mention to get the results we have to provide an email address – this is only necessary if you’re harvesting data for marketing purposes as the results could be provided without it).
You also have to remember, the forum’s owner would prefer traffic being directed INTO the forum, rather than away from it via a link to some online survey from an individual or organisation who probably doesn’t have a love or passion for walking and will most likely contribute little to the forum in the way of advice, trip reports, photographs or banter – we’re unlikely to “get to know YOU” and you most likely are not interested in US.
However, thanks for logging back on and eliminating yourself from the no-so-high accolade of “One Hit Wonder”.
