Gamers are complaining they are unable to delete their Activision Blizzard accounts, as they attempt to show solidarity with an e-sports competitor.

The US publisher caused controversy by placing a 12-month ban on a player who had voiced support for pro-democracy protests in Hong Kong on Sunday.

Users say they get error messages when they try to erase their accounts. Some suggest it could be deliberate.

But the firm has indicated a technical problem is to blame.

“There’s an issue affecting the site which our engineers are currently addressing… it’s a priority for us to have this resolved,” one of its North America accounts tweeted.

The BBC’s request for a comment has not yet been answered.

Some players in Europe have said they are able to cancel their profiles but have raised concerns that they are being asked to first upload government-issued IDs.

The firm has defended this on the grounds that it needs to be sure of their identity as the process cannot be reversed.

Activision Blizzard is behind some of the most popular console, PC and mobile video games, including Call of Duty, Overwatch, World of Warcraft and Candy Crush.

Now some players, who have been unable to wipe their accounts, are threatening to tell their banks to block the company from deducting payments.
