Try to search for the related blogs and forum so that you could get the best result out of it.
you can use multiple proxies for this. But dont repeat the proxies. By doing this surly your problem gets solved.
Through changing the proxies what would happen??? Is there any special trick for it.
Try to read a lot of forums and copy someone methods, when it works, keep doing it, when not, change it to another :)[/align]
My personal advice is, don't over use your proxies. Because this may cause some problems. So, try avoiding this for yourself. Other than that everything is a normal process.
