I'm sure the RFL are more than aware of a lot of the comments made on this site as well as others.
I did hear about a referee who was made to write a letter of apology to a pro ref (possibly silverwood) after comments made on twitter.
I'm sure theres far worse things been said about other individuals at the RFL which they'll be aware of, there's a fella on twitter (some folk will know who i'm on about here) who commentates for various organisations (including the RFL) who made the claim a few weeks back that Thierry Alibert was facing a 3rd suspension for allowing a try scored on the 7th tackle again, he's still not retracted this statement or apologised for it!
