You have accused minimaxir of being "Alex". Click on minimaxir's username on HN. You'll see he's been here for more than 1,300 days, and has information about who he is and where he is. Click his submissions link, and you'll see a bunch of his submissions. Not a single one is for any account to livecoding streams. (Although a stream of him creating on of his data posts would be interesting).
You probably need to apologise to minimaxir for that mistake.
You also need to find someone else to handle this thread, because you're not doing a good job at it.
Things you need to do:
1) Read up on your requirements under the various European data protection laws. You have to only collect the information you need; and keep it for the time you need it; and tell your users what you're collecting and why; and make the information you collect available to users when they ask; and make corrections when asked. There's probably a requirement to delete it when asked to too.
2) Fix your email. You must stop spamming people. Spam is any bulk, unsolicited, email. Bulk is "more than one". Unsolicited means i) You don't have a confirmed opt-in (and users not unselecting a box does not count in UK) ii) You don't include a single-click unsubscribe link in every email
3) Get someone who knows PR involved.
3a) Until then, get someone else to read your comments before posting. You don't need to post immediately, and doing so is causing you harm.
