Okay, whoever got my contacts to some other strangers from the fandom(all of them were greeting me in the request messages in a remarkable way of furries of course, that's for sure), that just really tucked my gun out of the pocket!

EDIT: Either it was MSN and Skype being integrated to Skype from the Live Messenger system, it could be a possible reason though because I can believe that some invitations might have been stuck there ever since(who knows since when). But it the case is that the sudden invitation was directly to my Skype, then here is what follows:
FYI: My Skype is confidential and not to be given away for others. You should have ask for it via note or e-mail maybe, before actually pushing me to add to your contacts.

If you keep pushing me this way, you are going on a really good path to trigger the hostile behaviour of mine be awaken.
