It is called Bitcointalk (BTT), not BCT.
First, let me correct you, it's either you call it Bitcointalk or BTT, not BCT.
Sorry for going off topic, but there are things I just can't let go

.
No, no, no fucking no. Don't spread nonsense. There's no logic saying BTT.
Let's break down bitcointalk :
Bitcoin
Talk
Bit
Coin
Talk
You can't write Bi Tcoin Talk ?? What does Tcoin mean ?
Do you say MS or MO for Microsoft ?
Do you say VW or VK for Volkswagen ?
And it's already been discussed in the past, the result is indisputable :
https://bitcointalk.org/index.php?topic=5121806.0Thought was the only one that felt the need to call it as it is...BCT

And incase anybody is doubting this correction, the trick is in the syllables which justifies the shorthand for
Bit
Coin
talk as it has three syllables in total, thanks for pointing this out again

.
Coming back to the topic, I actually see several users that do this, for example:
- Powerglove
- franky1
- Several mods/admins
- ibminer
And my observation is that such users are usually found in the Mining, Development & Technical Discussion board and Serious discussion board
