Ok!
I tried to locate definition for "spam" which would classify my previous short "quiet recommendation" (that's how I call it) as a form of spam , but I haven't found one

.
However, I LOUDLY apologize

to everyone who was affected with my spamming (although only one person mentioned it so far) and I promise that I will not continue with my heavy spamming in the future (because it is hopeless anyway - explained below).
I use this forum not very often but even so I realise that probably once a month there is a person here moaning about LaserWorld company's products so I wonder whether that is some kind of negative spamming

or simple human naivety

.
