Hello,
uCoz is a good free site builder. In the past it was pretty much Ad free.
Now it is full of very bad and big banners that move over the site content, following the viewer with pills for losing weight, naked people etc.
There are many quality sites made with uCoz but the ads are really forcing you to buy some sort of premium package.
The ads come in different sizes/shapes depending from which country you visit a uCoz type of site.
There is a very simple way to remove all these without getting your site blocked.
Use Ad Block Plus of course ! ( the best )
I therefor ask you kindly to include as default in the filter list of Ad Block Plus the following filter :
/abnl/
There are over 1 million websites made with this system and many of them are high quality but people don't have money to pay for the Ad removal packages. Don't worry the company is doing fine with over 10% growth in user base each year and the biggest site creation platform in Russia and growing everywhere.
Thank you in advance. Waiting for a reply.
