LEL is subject to AUK rules, of which 9.9.3. states "Riders who infringe AUK regulations, ignore event officials’ instructions, or behave in a manner likely to bring an event, an organiser, or AUK into disrepute may be excluded from the event and from future AUK events."
I think that covers all manner of anti-social behaviour, without me typing out a list of transgressions and penalties.
