Nobody at mi.doh.so deliberately collects email addresses or urls or names and addresses, from what you post in any comments made here, for unsociable reasons.
Any identifying information you may have had to use to get your words here is used only by automatic processes without human oversight. "But why have any automatic processes at all?", you may reasonably ask. It's to discourage spambottery. I am not in the business of mopping up your hailing frequencies, but I don't want my site compromised by spammers. If you’re reading this, and you’re apprehending it, then that’s fine by me. If you’re apprehending it and you’re also a robot, I'm suitably impressed and you’re very welcome to comment too – you’ll know how.
Which is not to say that others, including Google (who run this blogging framework), are not in the business of building up lists of email addresses (I'm pretty sure they’re not doing that here, but I shan’t speak for them is all). These pages are just as prone to Web-crawlers, spiders, etc as anywhere else, so do please exercise your usual due caution with your personal information.
