(I'm leading engineering at Algolia) Very sorry to read that the trial period you've experienced was that stalkerish. In order to provide the best customer & support experience to our users, we do ask our teams to do some research before reaching out to our users. I assume this went a little bit far in your case, most probably because you've listed the company you were working for on your GH profile?
Please feel free to reach out to me personally if there is anything I can do or anything you cannot share on HN, my email is sylvain@alg..
