Mine says June 2015, but I am a case where I signed up then, but was away for a couple or few years. I'd say I've been a regular for about 5 or 6 of the 8 years. When I initially signed up I had a different screen name. When that changed, the original membership date of the first screen name remained.

I've briefly stepped away a few times during the mentioned 5 or 6 years. Usually because of bully types, who sometimes calm their bullying (and all is forgiven) or sometimes leave or get banned. I've also briefly left when my own behavior was amiss because of bipolar episodes or feeling too triggered by something. I've never been suspended here. Sometimes blocking members (on both or either ends) can be a way to remain in more peace. And even blocked members can be unblocked.
