Having access to two machines at once is not the problem (although the use of multiple accounts by a single person is supposed to be strictly limited).

The problem is the sock-puppetry that's used to give a deceitful appearance of more widespread approval (or disapproval); an indication of probably-from-the-same-entity on posts negates the ability to do this. In at least three occasions you've followed up yourself, even going so far as giving yourself advice, apparently in some pathetic attempt to look knowledgeable:

• regexp for directory
• THCB
• bidirectional challange

At any rate . . . *plonk* *plonk*

Update: Useful CSS for marking the puppeteers. Replace the url with the path to a suitable image on your server (possible inspiration).

/* halfcountplus */
a[href$="668560"]:after { content: url(http://example.com/img/sockpupp
+et-icon.jpg); }
td.node-from-668560 a { color: #663; }

/* my_nihilist */
a[href$="673753"]:after { content: url(http://example.com/img/sockpupp
+et-icon.jpg); }
td.node-from-673753 a {color: #663; }

Quite reminds me of another puppeteer/puppet combo we had not so long ago.

(Really, note to sockpuppets: Do try to better differentiate your markup style.)

I have noticed a signature here about the significance of what is said and not who is saying it, but i don't know who said that

Um... It shouldn't matter who said it, right? ;-)
