I'm from Singapore and my ISP provides a dynamic IP address.
I've also looked up a bit about Singapore's ISP:
Anyway, here's the issue. For several years now I've been experiencing:
-Voting sites telling me that I have already voted for the day when I haven't
-Various download sites telling me my download limit has been exceeded when I've never visited.
- Wikipedia telling me that I have vandalized several articles multiple times on Grayman or soccer or something else when I've never visited the articles
Recently I've experienced:
-IP address-reliant account registration forms telling me I already have 3 accounts when I've never visited the site
I don't know if it's because of the Dynamic IP, but it seems logical that getting a recycled IP address would cause me to get blocked for things other people have done.
Also, I don't know if it's relevant, but my iPhone was not able to register for the IP address-reliant account registration when connected to my WiFi. However, it was immediately able to register when I disconnected and resorted to the 3G network (with the same email address and username, too!).
Does anyone know the causes of the above problems? Has anyone experienced them before?
