Rainer,
Actually, people do just that. In the past I've posted photos of animals with their locales, just to find that two to three groups of people then were around the same local vicinity within a week. Honestly, you mean to tell me you don't believe that people who live in the area where these things are found, won't hit the hills after seeing a snake of this calibur? It's not paranoia, it's fact, and it happens all the time. That's why it's best sometimes to post pictures of highly sought after animals after the season for collecting them has past. Myself, and many other zonata-folk have begun to practice this technique - as we're tiring of having to fix the rock and cover items in areas hit by people who surf these forums looking for tidbits of info of when and where to go.
And Joe is right, the site this animal came from is so fricken' small that a single person can decimate the habitat in a matter of minutes. Over the past six years I've seen eight animals at this site, and if people found out about it I guarantee you I would see no more.
