From the Insight book:
PROPHET
One through whom divine will and purpose are made known. (Lu 1:70; Ac 3:18-21) Although the etymology of the Hebrew term for a prophet (na·viʼʹ) is uncertain, the use of this distinctive term shows that true prophets were no ordinary announcers but were spokesmen for God, ‘men of God’ with inspired messages. (1Ki 12:22; 2Ki 4:9;23:17) They stood in God’s “intimate group,” and he revealed his “confidential matter” to them.—Jer 23:18; Am 3:7; 1Ki 17:1; see SEER.
The Greek pro·pheʹtes literally means “a speaker out [Gr., pro, “before” or “in front of,” and phe·miʹ,“say”]” and thus describes a proclaimer, one who makes known messages attributed to a divine source. (Compare Tit 1:12.) Though this includes the thought of a predictor of the future, the fundamental meaning of the word is not that of prediction.
So when the GB claims and claimed they are not prophets, they are effectively saying they are not spokesmen for God, and their messages are not from a divine source. In short, they know just as much a you and I do.
On the other hand, writing you never claimed to be am inspired prophet, while in fact you did so both explicitly (see Londo's post) and implicitly (by stating your message in from God, and your Spirit-guided) makes you a liar.
There is no honor in defending liars.
