These systems are only as good as your ability to hide them. Recently I did a trial of https://www.diffchecker.com/ https://www.diffchecker.com/, and when I didn't buy, got an email from "Nick from Diffchecker [admin@diffchecker.com]" saying, "If you're still undecided and have questions or concerns, please do let us know at: admin@diffchecker.com" and it was signed by this Nick person. So I emailed back briefly, politely explaining why I didn't buy. A week later, I got an email from the same email address saying "If you decided that Diffchecker Desktop wasn’t a good fit, we’d love to hear why. We’d appreciate if you’d answer these questions below to help us learn why didn’t you upgrade your subscription" asking me to fill out a survey. Outta here with that shit. Either you're being personal or you're not. You can't have it both ways.
