MI5 tries to stop me swimming (again)

You would have thought with rioters in the streets across the UK, police stations and hotels aflame and the courts overwhelmed with arrested ultra right wing protesters, that MI5 would have had better things to do than to block me booking a swim! But it appears not.
Of course it is possible that thousands of people were booking swims at Barrow Leisure Centre this morning and that was what caused the spinning wheel on my screen, signifying that my attempt to open the website was being frustrated.
Once again, it appears not. When I got to the pool it was more or less empty!
You might argue that it would be illegal for MI5 or its hacking team (GCHQ, probably) to find the social media posts promoting gatherings to riot, and then block them. Probably.
It is supposed to be a crime to arrange a riot. The spooks might not be able to stop the posts (though judging by what they do to me they certainly could) but they could certainly get the riot promoters arrested.
Be that as it may. Suppose there is some doubt about the legality of tracking down the riot organisers; there is certainly no doubt at all about what they are doing to my computer. It is completely illegal.
Those who believe I am paranoid and that there is no way the spooks would target me; should check out dozens of my posts (including about 100 videos on UA-cam) clearly showing that I am being hacked.
So could it be some weird hacking group. Not a chance. As well as the hackers I have also had to deal with a series of human interventions and attempts at blackmail. Hackers can't do that. MI5 can (and is).
