If we imagine ourselves that in tennis some players sell matches to others it will become useless to watch matches, everything will lose attraction. I started suppose that some of participants here at forum are here just because of some commercial interest, just for advertising of something or somebody. Again I can't teach anybody here or order how and what to do and this is their own affair, but I want to know who from participants ? (In order to take the fact into account when we are discussing something.) Frankly speaking, I started to suspect this when after my a few unguilty humorous threads some of posters had inadequate reaction to my frequent posts at forum as if I prevented somebody to do something. Do u have some opinion about the matter ?
