The number of people who have signed up is on the verge of reaching 200,000, including 326 new registrations on 22 February, a record for a single day since the service was launched in 2018.
Gamstop said the increase in efforts to avoid gambling appeared to have followed a rise in online betting volumes during November and December.
It said this indicated that “the trend towards more online gambling may be leading to more vulnerable individuals choosing to exclude themselves from all sites”.
More people than ever may have signed up to the scheme, but Gamstop’s figures also demonstrate the difficulty that many people have in staying away from gambling.
In January 2021, 49,328 people out of a possible 177,038 attempted to gamble and were stopped from doing so by their registration with Gamstop, which allows people to shut themselves out of internet gambling for a defined period.
