Liverpool have shut down 145,000 ticket accounts over the past two years as part of a crackdown against touting, BBC Sport can reveal.
They also issued a record 1,114 lifetime bans last season - a move that followed the discovery of mass manipulation of software used to buy tickets.
The Premier League champions said 500 people were denied entry to Anfield for trying to gain access with a burner phone - used by touts to avoid tickets being traced - in the last 12 months.
It comes after the industrial-scale black market in Premier League tickets was exposed by a BBC Sport investigation last week.
