Of course the guests will include GCHQ web crawlers looking for key words along with the other 5-eyes agencies that keep us safe, and also the Russian FSB, GRU & SVG who work as rivals each running their own operations, Ukrainian SBU, and all other intelligence agencies, including the EU and Mossad will be doing their job.
Just don't mention TB, culls, guns & bullets Pike or it will trigger one of GCHQ slowesh web crawlers, person of interest triggers. The real serous parallel processing and £££m are the massive parallel processing computers looking for key words in real time that ISPs must legally run in the UK and I won't mention TB, culls, guns & bullets Private Pike, and make TB a real person of interest that the mega fast Fast Fourier Transform analysis computers that telecoms companies must legally run and will now be looking for TB discussing culls, guns & bullets voice analysis keywords on the phone along with hot wiring his gay phone mike and camera in the bath which will put them off their tea, but they will settle again as they watch and listen to him watching his Samsung, LG, Phony or whatever TV. Probably, not a good idea right now for him as a person of interest to be watching RT, Al Jezeera news or ISIS terrorist videos.
This is the level of transparent intelligence we are all subject to, along with CCTV. All transparent so nothing for you to see here, please move along and get on with your lives, while our brave security force put theirs on the line keeping us safe.
Safeguards are a fine line and with the UK it is much finer than the US which after Watergate and Tricky Dicky Nixon have generally ironically been stronger than ours despite traitor Snowden and the rapist 'take the moral high ground Russian agent' Assange shouting from the hills otherwise.
I personally hate backstabbers especially those that commit treason like those two.
