As some visitors are aware, I used to have a Facebook Page for Ate Up With Motor, which was deactivated when I closed my Facebook account for good in December 2018. I had thought that I downloaded an offline copy of all the data from the Page along with the personal data from my account, but I recently discovered that I was mistaken, and in fact I actually retain very little of the content, comments, and messages from that Facebook Page. Since my account has long since been removed, it’s much too late for me to try to download that data again.
How that happened is a long, dumb story, but the bottom line is that if you sent me messages through the Facebook Page for Ate Up With Motor, left comments or posted on that Page, and/or shared media there, it is likely that I no longer retain or have access to that data. I retain a smattering of information in the form of old notification emails (and some bits and pieces of information that I saved or recorded separately for some specific reason, such as if someone provided research suggestions or article corrections), and I DO have an archive of comments and messages I sent or received directly (that is, as Aaron Severson rather than as Ate Up With Motor), but that’s about it. While people did sometimes share car photos and/or videos on the Facebook Page, I made a point of NOT downloading offline copies of that media unless the photographers had expressly authorized me to use their images on the Ate Up With Motor website (and I didn’t always get around to it even then, for which I’m now kicking myself).
It seems likely that Facebook still retains at least some of that information — for instance, if you are a Facebook user and left comments on the Facebook Page for Ate Up With Motor at some point in the past, those comments are probably still listed in your Activity History. Questions about what data the Facebook service retains and/or what options you may have for accessing or deleting it should be directed to Facebook, as that is beyond my control. (I almost certainly lack the legal standing to compel Facebook to delete someone else’s data.)
ETA: I have also discovered that the archive I’d made of the long-defunct Ate Up With Motor blog on the LiveJournal service was no longer accessible. Again, I may retain certain related information in other forms (e.g., notification emails), but most of the data has now been deleted, and the blog itself was purged in 2014. I don’t know if the LiveJournal service retains information about comments or messages still-active users sent to blogs that have since been purged; I haven’t used that service in many years because I refuse to accept their current TOS, the only binding version of which is in Russian.
