[Skie]

There was a spate of phishing/scam emails not too long ago where people were receiving blackmail emails, basically "we know you visited greasygrannies.com and will make this public knowledge if you dont pay us £1k in bitcoin".

Whilst it was just a scam and the websites weren't actually visited, imagine those guys actually got hold of this database: they'd know what sites you'd submitted and could make fairly accurate threats and possibly even follow through on them. The original attempt was just a mass spam attempt to hopefully get a small number of fools, but actually being able to target people...
