these are probably the people more interested in getting someone to sign off on a bug bounty than they are in getting hold of someone technical who might point out that the fact you can right click and edit the HTML to say "HACKED!!" isn't a bug...
When I had an issue with LastPass, the ONLY contact method they listed for support required you to log in and use their help form...
Since I used federated login, only the browser extension was supported -- not website login... So.. I can't log into their website for support, but I have to log into their website for support...
I went through a series of help@ support@ helpdesk@ contact@ and got bounces / "use our web form" responses... I then escalated to the other technical addresses like webmaster@ hostmaster@ until I finally tried to reach out to sales@ for the support issue...
So sometimes people do intentionally write to 'the wrong address' because there's no 'right address' (that's publicly known/available).
