Doubble M:
You should actully check your facts as although some hit counters can be made to count non repeats some ISPs such as some cable providers have the same IP address for all their customers so they would only count 1 hit from any one with internet from that provider. Also not many people want to use hit counters which only count 1 hit per visitor as websites which make no money or make a loss want to have a large amount of hits and members because it makes it more appealing to other companies who may want to buy the website.
Also as well as harvesting information and sending emails botnets can make other computers do other things with out the computer owner knowing such as visiting websites. Usually botnet owners can threaten a website to pay money or they will make all the computers on their botnet visit a website at the same time and cause the website to slow down or make the website not work due to the large amount of visitors. If a botnet was made to visit a video on you Tube even if You Tube had hit counters for individual views (which it doesn't) it would count each visit as a hit.
ACTUALLY - I do check my facts - - - I suppose along with every customer having the same IP address they All share the same cookies too - - but since you are so knowledgeable please give an example of an ISP that has the same IP address for ALL customers.
The IP address is but one of numerous ways of telling if a person has previously visited a website And Each ISPs customer has an individual IP number for a very good reason and it is not for telling which websites they have been to
I do not claim to be an expert on any subject but I do ensure that what I post on any subject is accurate - - I do not post messages as you do that are full of Assumption, Speculation and Supposition
Before you attempt to make somebody else appear as though they do not know what they are going on about - maybe you should do some research on the topic befoe you post messages containing information that is inaccurate or just plain Wrong
If people research a topic properly before posting about it there is less chance they will make a fool of themself posting stuff that is wrong
