Although it is very easy to realize this is a troll, you did not make it far too obvious by using smileys or other rookie-troll techniques. Keeping the text short was also a good idea, since maintaining a convincing level of retardedness in a long text without exaggerating needs advanced knowledge of trolling.
Also, I like the way you used the last sentence.
"Ya'll at /a/" is a good way to imply that you yourself do not belong to that group, thus strengthening the belief that you are from gaia.
There are some obvious flaws, but I'd say your trollfu is higher than the average fag. All in all, a decent troll. However, low level techniques can only get you so far, even if you do perform them correctly. Looking forward to see your development.
