🧱 Lego's BrickLink marketplace goes dark after 'unusual activity'
Lego has kept BrickLink, the popular second-hand Lego marketplace, offline for days while it investigates an unexplained problem.

The mystery
Collectors around the world use BrickLink to trade Lego sets and rare bricks. Suddenly the site went offline, at first labelled as maintenance. What happened, and is anyone's data at risk?
The answer
Lego, which bought the fan-built platform in 2019, says it spotted unusual activity and wants to fully understand it before reopening: containing the problem, investigating the cause and checking for related issues. It has not said whether the site was hacked or whether customer data was affected. The site had been down for at least three days, and a promised reopening time was later removed. Separately, a long-time collector told the BBC she was asked to pay twice for a pre-order; that has been fixed, and it is unclear whether it is linked.
Now think about this
When an online shop goes quiet without explanation, what should companies tell their customers, and how fast?
