A lot of this information can be obtained by doing a very simple Google or likewise search,there is enough good search engines out there, but I find that some people want the very easy route, and request that other people do all the leg work for them. Okay, giving advice and suggestion about the 'best' available product, can cut many corners in the learning curve, but at the same time, what is the best product, as this would depend on the person supplying this advice.
In the case of the PCA forum. how many days go by without someone asking the exact same Anti- Ad-ISP question, when a previous days read or simple forum search would have perhaps supplied the answer many times over.In fact, it was only recently that someone stated that they did not have time to do a search.Statements like that make you want to think, if that person really requires help of any kind.Bit like the person spending two hours or so in a leisure gym everyday 'limbering up'with the glass of wine at the end, and classing it as their extremely very hard working life.
Appologies if this sounds like a rant, as it was not intended to offend.Just my personal feelings.
