I'm not reading the forum as often as I'd like to, but I was notified my group was mentioned here.
steph Arnott is right. The issue, from its technical aspect, is minor. That is why I prioritized it as minor on that jira ticket. But the case still remains mysterious, if not weird. ChinRey only expressed what many members of that group ask(ed) openly or privately: Was our group the only one changed? And if yes, why?
According to Caleb Linden, there is a procedure which strips those leading spaces. According to Whirly Fizzle, this procedure is buggy. According to this thread and numerous other experienced active residents, no one can indicate a similar group which is changed, besides mine, several weeks after the change was happened. Conclusion: This new procedure picked my group first, "fixed" it, and then stopped working.
I'm sure the fact our group was created as an in-world public forum for Project Sansar and also the fact LL seems to be a bit nervous, lately, about the kind of publicity their new baby receive, is just a coincidence.
To avoid misunderstanding: I'm not talking sarcastic. I do believe the change wasn't really made manually. Our community is not oriented against LL practices, after all. On the contrary, we are all Sansar enthusiasts whom only goal is sharing news about it and talking about how it can be a great next generation platform.
However, to some members, what seemed to be a selective treatment was taken as some kind of an intimidating warning for us to be very careful of what and how we discuss our topic, thus conversations dramatically decreased.
So the real issue here is not LL to change the group name back, but for us to have an example of equal treatment which I could use to prove the silliness of the conspiracy theories and thus to restore group's functionality.
Unfortunately, when I asked for such thing from Support, the official answer was that providing a publicly available information, such as a group's name, would become "an issue of a privacy concern"(!). (the full dialogue with Derrick Linden, Support Supervisor, is going to be available to any of our members, as he allowed me to copy-paste it at will, but I won't paste it here, on forum)
I'm not sure if ChinRey wanted to help the community by taking the initiative to search for that 1 example or she was simply curious (if first is true, I thank her), but I do know she doesn't believe on such speculations either.
PS. Creating a new group with a leading space is still possible for anyone.
