A social media user is behind a crusade to expose illegal and inconsiderate parking by drivers across Hull and the East Riding.
The Twitter user, who goes by the name of @Hoga4, has taken thousands of pictures of unsuspecting motorists and their badly parked cars, vans and trucks.
From delivery vans to taxis and bangers to sports cars, the parking enforcer, armed only with a mobile phone, has revealed to the world thousands of driver errors.
Whether you are at the supermarket, at a petrol station or the shops, it seems @Hoga4 could be watching and documenting your every parking indiscretion.
The volunteer traffic warden's obsession has attracted more than 3,000 followers, who are treated to scores of pictures of badly parked vehicles every week.
Earlier this week, his targets included a van "parked across two spaces" at a supermarket, a car "with no kids" in a parent and child space and a family hatchback with the message "she never even bothered to try and park within the bay".
His beat seems to include much of Hessle and west Hull. Supermarkets including Sainsbury's superstore off Priory Way and Aldi in Beverley Road, Hull, are also hotspots.
The sheer scale of his effort is evident. @Hoga4 has tweeted more than 15,500 times, largely pictures of badly parked cars.
Despite numerous requests, @Hoga4 did not wish to comment on his parking snaps.
However, both Hull City Council and East Riding Council urged people to report parking infringements in the correct way.
A spokesman for East Riding Council said: "If anyone has any concerns or wants to report illegal parking they should contact the council's civil parking enforcement team for them to investigate."
The city council has launched a new service to help tackle fraudulent blue badge users in the city.
There are 12,000 blue badge-holders in the city, held by people of all age groups with a range of mobility and other disabilities.
It is a criminal offence under the Road Traffic Act and Fraud Act to use a fake, lost or stolen blue badge.
