Using HotSpot Shield is it possible someone may trace my location ?

[Alderen]

This is a two-part answer

The first part being that Facebook and twitter do log your IP address in their system. But you have to keep in mind that that information is not publicly posted and is securely kept in their servers. Someone would have to break into the servers and retrieve the information before they can even start a trace.

As for your concern about having your hotspot Shield and your IP being traced that is always a quite possibility. But if they are being changed over time is unlikely that someone will trace you. Of course we're talking about people and most people that even know the first step into tracing someone with IP addresses.
