You might like to consider that the BBC also have valid reasons for knowing the postcodes of its viewers. Perhaps they want to know what programmes interest which people are in different regions so that they can tailor their services accordingly? https://www.bbc.co.uk/usingthebbc/account/why-do-i-h...
Regions wouldn't need the full postcode.. They could ask for the first bit.. this is one of the reasons we don't ask for house numbers on speed tests - we don't track speeds down to houses but to postcodes hence why we ask for that. In the end they can indeed ask for this but they REQUIRE it... we don't.. we give you the option and we limit it. Requiring data can result in people giving you bad data. In the end we provide data on broadband to everyone on the site..
I have never, ever received marketing material from the BBC.
TV Licensing letters are marketing material
I notice that you require an email address when someone creates an account with you. Why? That is arguably more intrusive than a postcode, which covers several households.
This is quite normal for accounts on just about any site. We're perfectly happy for you to use a specific thinkbroadband@yourdomain type e-mail address if you prefer (or an icloud unique one which doesn't identify you).. We don't always stop the 'throw-away' e-mails but they are more likely to be banned because bad guys abuse them for spamming, etc.. One off e-mails aren't fake per se and not a problem.
BBC require you to register for iplayer.. We don't require you to register to do a speed test.. we do for BQM as we need to only allow the right person to edit it and view it. Also when we get complaints about pinging someone we need to contact whoever created the monitor. Speed test is a one off thing so hence it's only needed if you want to track performance over time.
And unlike any utility companies/banks who sell the e-mail addresses for age verification providers - we don't.. We don't even target marketing on any other channel so we don't do facebook ads, etc.
(Note. I've no objection to either - just to the hypocrisy of criticising the BBC for something that one does oneself. But then, the BBC is a favourite target nowadays.)
I like the BBC and I'm licensed (mainly as I use iPlayer occasonally). I don't object to them in fact I like their content. I don't like how TV licensing letters are both incorrect and become increasingly abusive. I don't condone anyone not being licensed when they should be.. but they shouldn't be hounding people just because they don't have a license, with letters that make dubious claims.
