Not concerned about his volume (lack of) posts per se. More the situation that he is acting so so suspiciously; and along with the lack of posts - we cannot possibly gauge anything about the chap.
He chooses to reveal zero of himself, and I personally think that speaks volumes.
Again, just in my opinion, I would not ever enter into negotiations, pertaining to a high risk (window cleaning takeovers are always high risk, unless the vendor demonstrates to you that he is beyond suspicion) business purchase, with those engaging in such dubious sales tactics.
It appears at this stage that the vendor does not intend to address our genuine concerns.
So, PLEASE exercise extreme caution; I strongly advise we ALL refuse to play this NDA game!
If you sign an NDA, you throw away most of your usual safety net. You will not be able to discuss or verify, anything claimed by the vendor, with any one whomsoever! WHAT HAS HE GOT TO HIDE???
