Ah I see.It's more about the fact that these places aren't always easy to access and also can be quite hazardous. If no one knows your abilities or risk appetite then they could just be agreeing to take a complete liability with them. It could end in getting arrested, failing entirely or having to get someone out of a site after they've injured themselves.
Posting reports demonstrates to other members that you are actually serious about exploring and also that you have the common sense and capabilities to tag along with them.
The cons outweigh the benifits of taking new members along with you so most won't bother making the effort if you haven't made any effort to get out and find things and contribute to the community.
That's interesting and makes sense. Thanks for explaining.
I'll have to find a few places to explore myself then.
