I believe the phrase that applies here is "put up or shut up". If you have hordes of documents to draw on as primary sources, then it should be pretty simple (but perhaps time consuming) to write a rebuttal.
just gonna guess here. Were you “invited” because you had signed up with Codesmith under an alias and then received a standard event invite? because it doesn’t sound like anyone at Codesmith would be personally inviting you.
