OK
I think you got the answer to your question.
All short meaasges , or even long ones without subject or that have nothing to do with the topic are considered as spam.
Multiple posting on the same topic in a short interval is also considered as spam as you could obviously have put all your comments into one long one.
No more replies are needed I think, as they would be a repetition of what was said.
If you have more questions, don't hesitate to ask the moderators and don't forget to consult the Forum rules
