Should you submit a comment, the comment will likely be posted to the website but this is not guaranteed. A major problem is automated "comment spam", much of which is criminal in nature. Other problems include hate speech and posting of copyright material. I use some simple algorithms to dampen this noise while retaining good comments, but false positives and false negatives happen. So your comment might be blocked.
collection and use
I collect whatever you submit. I use it for responding to commenters, and for publishing a name next to every comment submitted with a name. Your email address will not be published (the comment submission form does not require an email address). I will not share commenter data with a third party. From about 2007, I used a "gravitar" lookup to put a face to the email addresses used by commenters, but eventually came to realize that this was a violation of a commenter's intent of providing the email address and stopped this practice in 2016.
So far, I've been storing data submitted by visitors "forever". That will likely continue. I have and will continue to remove the comments, names, and email addresses of submitter upon request.
No guarantee of privacy is extended to anyone submitting data. To be clear: data such as name and email address is stored on a system directly connected to the Internet, and there is no budget for guaranteeing complete confidentiality of such data, because that is not possible at what I'm willing to spend on securing the site. Because this is not a for-profit website.
