I finally went nuclear and let Facebook delete my account completely (e.g., I opted to delete rather than deactivate and 14 days has since passed). I then created another account under a variation of my real name, to keep with its TOS, and now use it solely to administer my groups and subscribe to the commercial feeds of businesses and brands. I find a company's Facebook page often "better" than their WWW pages because they can't ruin the presentation with monetization techniques or a futile effort to make their content work on PCs and mobile devices -- which usually dooms them on the PC. I maintain zero friend connections and don't use it for keeping connected.
Empty WBRAIL Facebook Group
The tragedy however is that my groups were all essentially reset in terms of content. Since they largely contained content posted from my now deleted account, including the logo art, it has all been deleted as well. They look barren and empty. I'm a little upset because over time I had collected a great deal of worthy commentary and link pointers to various articles and artificats of progress in each topic area. Now it's all been wiped out.
I'm debating whether to re-post what I can of it all, or, just abandon the Facebook groups altogether. I can restore a lot of of the links and commentary, I suspect, because I have my Facebook archive downloaded and would find little trouble in manually re-posting every entry since each group began. However, the whole thing has turned me off from using FB as any kind of a content management system because now it appears you have to keep an account alive forever to develop any meaningful history on it.
Each campaign, WBRAIL, Tampa Rail, BuffaloScan, all still live as Twitter accounts and the respective web pages here at DWG. And most of the links here were the same that appeared in the FB groups. I think for the foreseeable future this is how I prefer to keep things.
