Suppose there is a question, "How to get started with applying item response theory and what software to use?"
Suppose the top-rated answer cites my name and work a couple of times.
Suppose all answers discuss software, which is what the question asked about.
Suppose I have a new piece of software, and I tell people about it, as this was what they asked.
Suppose my answer gets immediately deleted by a moderator with a message, "We're glad to have you, but unfortunately this isn't the place for such a description of your software." Did the person even read the original question, in the first place? Would he or she be qualified to understand the value of an immensely complicated psychometric package being released, free of charge, to the community?
And -- what can you do?
And -- who and how defines "overt"? How is a single recommendation of a freely available software package, provided as an answer to a question about such packages, on a page that discusses packages top to bottom, "overt"?
