I think what they meant by 10 disclosures was that there WAS information to be disclosed in those 10 cases, in the rest there was no information.
the way I see it of the 150 enquiries it breaks down like this
71 were being made by people who had no need of the information (so they were discarded)
79 were made by people who were in need of the information
10 were about people that had relavent information on record
by your standards if you ever felt your girfriends breasts before she was 16 years old, even if it was a fumble behind the bikesheds at school and was through her clothes) you had better go and turn yourself in to be added to the list.
( I am assuming you are a straight male) if you happen to be a homosexual male then its even more confused as to whether it was legal or not with changes made to the age of consent (varying from 21 years old to 18 and then to 16 in the past I believe)
I am not against the idea behind the law, but more thought needs to be given to what should or should not be included or how the information is presented.
2 examples.. both now 45 years old
Mr Jones at 16 was sleeping with his girfriend who was 15 years old with her parents blessing, someone reported this and Mr Jones received a caution but no further action was taken, Mr Jones is still happily married with the girl the was sleeping with and they have children of their own.
Mr Smith at 40 years old was caught with his hand down a 10 year olds knickers, and was convicted.
a report on Mr Jones would record that he had received a caution for having sexual intercourse with a child
a report for Mr Smith would record that he was convicted of interfering with a child
given the current reporting method in your eyes both people above are branded peado's and cannot be trusted around children, given context you can see that Mr Jones is not likely to be a threat but Mr Smith is very likely to be a threat.
