We've been discussing these issues, amongst others lately in the Fediverse-City room on Matrix, what with the relative demise of Meetup.com following its acquisition by WeWork, and the rise of *eve...
Recent progress in the world of event management systems and interoperation between the vast expanse of instances and platforms in the Fediverse looks really promising in the coming new year - so much has been accomplished!
My first thought was that it was probably a DoS. Neenster is controversial, one of the most frequently blocked sites on fedi. That's in large part due to timing, I think. If it were newly invented today, rather than coming to prominence just at the same time as it became fashionable to apply giant blocklists without having the slightest idea who you were blocking or why, I don't think it would be quite so thoroughly cut off. Not that I agree with all of Nina's unpopular opinions, but she's usually not too obnoxious about the politically sensitive stuff that gets her into trouble. Or she wasn't, back when I used to hang out in the sort of place where I heard about that stuff. But anyway it makes me wonder: What if some day she's changed, and is no longer objectionable in the ways that people thought she was? As it stands it seems like she'll still be blocked forever, and that seems unfortunate because in addition to offending people she's made some great art and other worthwhile things.
But no, it's just some stupid javascript problem. In order to load the page try a fresh disposable contanerized browser profile without ad-blockers, or whatever other hazmat procedures you prefer.
That seems like an extremely sensible idea. I've signed up for a few events via the usual websites, and every time it seems like a cruel indignity to have some wannabe technofeudalist upstart forcibly injecting itself into the process as an intermediary.
