Kate, the old ones who may choose to leave will still have been 'force-flagged,' and any potential repercussions will remain; any damage will have been done.
As Simon commented 2 years ago after the first time the country identifier problem came to light:
[EdenOne] And yes, of course, to reveal the geographical location of a poster is just as serious. Especially if that country is a small country with only a few congregations, where basically every JW knows every other JW.
[Simon] I want to answer this in more detail:
While the overwhelming majority of posters are from large countries and regions that cover a large physical area or population (e.g. US states) I take privacy very seriously and obviously rectified things immediately and apologise for it happening. It was due to me combining two code modules: part from the current site which let people set the region and country in their profile and part from an anti-spammer module which identified regions and countries from an IP address - at some point I referenced the 'wrong' region/country pair to update a profile and didn't notice because all the ones I randomly checked just happened to have their location already set anyway (which matched).
The reason for not 'announcing' it was to not draw attention in case of a very slight risk that someone could possibly be identified from it even though I don't think it's likely, if even possible (it would neecd other information to be exposed as well). Unfortunately, Cedars seems to feel it is a risk worth taking by highlighting it.
I've been busy building in some other features to help protect people's identities further and ensure this site continues to be a safe place for already-out or questioning-JWs to visit. [underlining mine]
Simon recognized that there was a very slight risk of somebody being outed by the country identifiers and that, because he took posters' privacy very seriously, the issue was quickly resolved, the flags removed and an apology given.
It would be nice to see a return to the same level of care and concern about individual posters' privacy expressed two years ago. The risks may be 'very slight,' but if a force-added country flag contributes to just ONE person being outed, then there has been a dereliction of duty by this forum to do its utmost to protect members' identities. It's one thing for a poster to out themselves by being careless. It's another for a forum to willfully display a piece of personal information that a poster wishes to remain private.
