does any one no of any 
Do mean people who do it ?.
Or those smart zbās who think they have a one so good, so original that no one else has ever thought of it, or that they are so zbāing clever that they, unlike everyone else, are going to get away with it when someone who knows how to manually analyse a chart looks at theirs ?.
If the latter donāt forget that the VOSA & Police also have the right to any & all paperwork that may help in the investgation & that unlike the average trucker trying to pull a fast one, they have time on their side & also a tiny bit more intelligence.

None that are worth risking your drivers licence for really. 
Did you want to use them or just to know to tell your friends about? 
To be honest itās probably not the best first post, but nevertheless, welcome to TruckNetUK. Some forums have a welcome pack they direct to new users but here you just have to ask 
Cheerio
Iām not too sure about the ābit more intelligenceā, Smeserver. However, as far as I know, every one has been done and spotted before. So all they have to do is spot the tell-tails and check. There is the evidence neat and tidy. So they donāt just do you for whatever offence you where trying to cover up, they do you for falsifying legal records as well. For that, they throw away the key.

Quite true; knowingly make a false record = fine of upto Ā£ 5 000 and upto 2 years in a small room with a lousy view. Probably better to keep it legal as most fiddles can be easily spotted by a trained person.
Keep it legal for everybodies sake.
You only end up cheating all the drivers by keeping the rates down.
