It has been demonstrated that on 8chan, you can have a space or not. Both of these are equally valid on 8chan:
<name>#<tripcode>
<name><space>#<tripcode>
Because of this great confusion, Q has just now decided to remain consistent with the way halfchan presented his name and tripcode. Thus, he's now using the second form. It doesn't really matter which you see. The tripcode is legit if it is non-bolded.
