Re: Not proportionate at all!
This is in the UK not the US. I'm not aware of any cases where "civilians" (which I interpret as meaning people who are not police officers. It would also exclude terrorists.) got 20-30 years for hacking offences. Perhaps you could tell us about some?
Your claims also run directly counter to the article itseld. The final paragraph reads:
"Statistics show that prison sentences in Computer Misuse Act cases are unlikely, though some offenders do find themselves behind bars, usually if a victim suffers financial loss or similar harm."
It even includes a link which notes that between 2008 and 2018 only 16% of those found guilty were given an immediate custodial sentence. So, can you provide some counter-evidence to support your claim that "A civilian certainly would not get mere community service." The facts show that yes, many many civilians get precisely that.
