NecNecco on "Am I on Hack Attemt?"

Hello all,

I am new to Support but proud to be a Wordpress'er.

I am seeing three weird url attempts in my server logs. URLs are below:

http://example.com/?p=325++++++++++++++++++++++++++++++++++++++Result:+chosen+nickname+"ExaxySwanna";+sent+(from+first+page)

http://example.com/?p=325++++++++++++++++++++++++++++++++++++++Result:+chosen+nickname+%22ExaxySwanna%22;+sent+%28from+first+page%29

http://example.com/?p=325++++++++++++++++++++++++++++++++++++++Result:+chosen+nickname+%22ExaxySwanna%22;+sent+from+first+page

Would you mind interpret what are they trying to do please? And do I need to get worried about this attempt?

Cheers
