Nothing rude about it. Not in the least. You have to expect people to comment on the obvious and the unusual. Your two most recent posts refer to "friends" whom you seem keen to report as fraudsters. Not the usual grist for this forum.
Before your recent edit, you asked:
"Does anyone know if the required info (listed below) is missing from the invite letter, will it still be considered sufficient for the application? Someone I know wrote it on behalf of a person living here in Canada. can this be reported as fraud?"
Now you say, and ask:
all i wanted to do was report a fraud case of the invitation letter. simple. does an invitation letter hold value in a visit visa application?
Those matters are really quite different. Your original question, about whether an invitation letter with missing information will be deemed sufficient, would seem to yield the simple answer: "No, it's missing information the IRCC instructions say is specifically required, so you can fully expect the IRCC to regard it as insufficient."
As for your recent question: "does an invitation letter hold value in a visit visa application?". That question makes some sense and the answer I would give is that a properly constructed invitation letter will be of value in some cases. But, I would say it won't help much if the application is otherwise deficient. By that I mean that if the applicant is unable to show the usual things, such has having sufficient cash of their own to fund the visit, a solid travel history to countries such as the U.S., the U.K., etc., a solid employment record, ownership of assets and so on, then a brilliant invitation letter is unlikely to carry the day.
