I'm assuming you know %20 is really a space. I've apparently been getting some of those visits too, as I got a whole bunch in my WMT Crawl Errors starting 4/5/2012 and increasing in frequency daily. Of course when you check the error report, there is nothing listed for "linked from". The base pages appear to be totally random. I thought at first it was someone trying to link incorrectly (accidentally putting a stray space before the ?) (perhaps a programmer at Gbot :). Without the space my server would serve up the correct page and throw away the parameter list just fine.
