What is Tesseract?
An alternative frontend for Lemmy. Its developer has a track history of being rather unhinged, and has recently become even more unhinged. He apparently feels that it is his job to police the content on all of Lemmy according to his own whims, and was recently caught secretly inserting a long and complex list of content filters and user blocks into his client as well as pushing purposefully misleading error messages within his app to obfuscate this behavior. The explicit bans of specific users has attracted the most attention and amusement from the community writ large, in particular from the people who are banned. Note of course that this list happens to contain yours truly, for truly unfathomable reasons.
He previously ran a Lemmy instance (dubvee.org) which was infamous for preemptively banning huge swathes of users from other instances who had never even participated in or even visited his instance. This was shut down or rather more likely made private some time last year after a high profile crash-out by the developer/operator.
Damn. Glad I’m on Voyager
