It makes me sick to my stomach to read the tactics of those in my industry and it is a real shame to see an industry which should be there to help, in fact becoming a hindrance.
I wish all the terrible recruiters could just be weeded out and removed...
Since this is nigh on impossible I agree with the article's point about keeping a record. Some of us are passionate about what we do, some of us love startups, or tech, or people, or all of it and will give you a service worthy of a fee.
I do not work withing the UK industry, as I became disheartened by the hate (if you need help in Germany however...), but I can highly recommend companies like The Up group - to whom I have no affiliation - as I understand their service is brilliant.
Those that are less worthy of praise are pretty obvious - just search out Milo Yiannopoulos' Kernel mag articles....
