no it's not.... 'I've definitely learned something from his site' So then eveything is ok. Whould you think the same if the site planted spyware in your computer, viruses, uses your email to send spam...what price do you consider to be ok to pay... 'If you have a problem with popups, don't visit the site' That's just my point. If I had known that there should be popups I could have made a choise to not visit the site but as I was not warned in advancer I had no way to know. 'or take the precautions' There is a limit in how much work and time I'm prepared to waste in order for other people to make money. I'm however not against ad sponsored sites if they do it the nice way (such as the add in the top here at renderosity) but when forced to close popups or make other precautions I don't. Popup ads, spam, spyware and virus are considered to be anoying by a mayority of users. And it cost's time and money for both ordinary people and companys. Goverments are reacting to this and planting viruses is illegal. Sending spam is illegal in some countries and more will join. Popup ads is the least problem but still around 70%-80% of the users hates them. Because of this I think it's better to do what's possible in order to minimise popup ad's rather than support the use of them. In real life I prefer that the criminals are behind locks and bars instead of putting myself behind locks and bars in order to be safe.
