I am sorry you have not got in on the dates you wanted. Some of the points you raise are valid.
First point: it wasn't anonymous information you asked for - you wanted to know which clubs and individuals had been on trips (and you are still asking for clubs to be identified). I personally would not want my information shared.
Second, not every trip is arranged through the permit secretary, hence not all trips will be logged centrally. Many trips have a working objective (diving, conservation, whatever).
Third, the people who take the trips are (obviously) volunteers and not many (none ?) would take mid-week trips.
Fourth, there are a limited number of days (although still quite a few) when the tides are suitable for a trip (especially over tide) and you would get few wardens keen to start a trip at (say) 5.00 in the morning.
Fifth, relying on a forum member (and yes, I do know who ship_badger is in real life) to raise your concerns is not the best way to represent your views. Put pen to paper and write (I shouldn't have to spell this out) to express your concerns. Really - not many people active in the Forest read this forum. Also, think how your points will be raised "Some random person, Dave_the_cave, who is upset at not getting into Otter this year - yes, yes, I know it rained, is threatening to speak to the land owner and attempt to disrupt the long held access arrangements. He is complaining on a public bulletin board. Now, how should we address his other complaints ?". Really, truly, write a letter. You actually do raise some points that need to be discussed. You are just not being very sensible about how you raise them.
Finally:
Threatening to disrupt access (which you would) by directly approaching the land owner (when you clearly have absolutely no idea about the access arrangements with said land owner) is inflammatory and quite possibly not the best way to endear yourself to the volunteer guides and cavers in general.
By making threats like this on a *public* forum any sympathy interested parties may have for you will quickly evaporate. I would suggest (as I have before) that raising your points with the club that controls access is a more sensible and productive approach.
By the way - since you want to share information on other people and their club's trips:
What club are you from and what is your real name ?
