Ditto what Harpsi says about being pragmatic, and great posts too from last night.
There are other steps that the court may have been able to take, though I don't know if it did.
He will be on the Sex Offenders Register, requiring him to report any change in living circumstances,and he will be visited albeit on an infrequent basis by a local police Sex Offender Management Unit.
Also, the courts can/may have made a Sex Offender Prevention Order ( SOPO), which would specify things he cannot do. In this case it may be a ban on him having possession of a computer, or accessing the internet for a defined period.
If the court are making such a light disposal of these offences, it could have at least backed it up with a v. restrictive SOPO. No idea if it did though, but given we have not heard of this, it probably didn't.
