The legal efficiency of "I do not represent..." disclaimers are dubious at best, but here's me covering my ass:
All views and opinions expressed are solely my own and do not express the views or opinions of my employer/s (or other related professional affiliation/s) past, present or future.
I am not authorised to represent my employer/s online, except where explicitly specified.
To be absolutely clear, all the above includes any views and opinions on any and all websites I run, (e.g. my blog) and all social media.
Still want to yell? Go back and find my email...
