i dont no if anyone has thought of this or not but would it be possible to make a plugin to tell if one of your contacts is ignoring you by telling you if the contact is having conversation with any other contacts

It would be impossible to detect if someone is having a conversation with others, so this is not possible.

Not impossible, but would require a plugin (easy code ), but would also violate a users privacy .

it would only violate privacy if u could use the plugin to detect what they were saying to other people, if the plugin, was just used to detect weather there was any outgoing information form there computer, it not exactly a invasion of privacy,

Why don't we just make a credit card number, home address, phone number and SIN locator?

Many people have requested things like this and block checkers and such, but they won't happen because they = privacy loss, and would ALSO prob. require both ppl having this plug-in.
