I often see it mentioned that Aimee Challenor developed the Terfblocker software. Sometimes people say that Aimee developed it in conjunction with her father David.
Is there any evidence for these assertions, particularly the second one? I found an old Mumsnet thread containing screenshots where Aimee seems to acknowledge being behind Terfblocker (saying it has 50,000 names on it) and also that she is developing a new one, but I've also seen a tweet from Aimee denying having anything to do with it. There doesn't seem to be any evidence that Challenor senior had anything to do with either pieces of software. Here's the thread where it was discussed before:
