Re Bugger me
I wasted a happy half hour trying to report the Patientline pump & dump to a regulatory authority.
It was hard enough trying to find _who_ should receive such a report; and even harder to find contact information for them.
I eventually spent about 10 minutes on the phone to a very bemused gentleman who I don't think quite undertstood why a member of the public would be trying to make a report on such an issue.
My general conclusion - for the time being you can P&D on the UK SE at will, as no-one in authority understands the process well enough to do a damn thing about it.
The patientline one was utterly blatant - I think I received over 100 copies of the mail - and as "anonymous vulture" noted, noticeably affected the share price.
