We can't know who did this without more information (how about link to the thread?). The real question is why does this matter to you? That whole thread is garbage.
Thread is here:
https://bitcointalk.org/index.php?topic=686828.4260The thread was loved by many users, and got many thousands of views, it's so hard to call garbage.
This is more about envy of so sucessful thread.
Someone was so heartburning about my asking of quality of service of one site, that he began to complain of my other messages.
The real question is why does this matter to you?
I'm worried if such removal may lead to ban.
