Most of the EU countries have an opt-in policy: no unsolicited calls are permitted unless the company calling you has your permission. But that's not the case

Most of the EU countries have an opt-in policy: no unsolicited calls are permitted unless the company calling you has your permission. But that's not the case in e.g. Belgium, where I live. Belgium has a do-not-call register. Last week, I made a tool to automatically add phone numbers to that list (the do-not-call website API was unprotected,and all I did was automate what anyone could do manually via the website) so that we'd arrive at a de facto opt-in situation, but at 700K numbers the do-not-call website went into maintenance :)
