Sorry, but no, it's not OK. We realize that only a very small percentage of new members are potential scammers and that this minimum post/time stipulation may seem like over-kill and is cumbersome for some, but it is in place to help prevent scamming and we don't want people looking for ways to circumvent the rules no matter how good the intentions. We have enough trouble trying to be consistant with the rules as it is, without having to make individual decisions on whether or not this rule or that should be bent because of unique circumstances.
While it may seem harmless and fine to some to act as proxys for others wanting to sell or make purchases in the For Sale Forums, there's still the potential of scammers using this rule circumvention to prey upon our members. For example: Many head-fiers want/like to be helpful whenever possible and most scammers are shrewd as well as unethical. If we start allowing members to circumvent the rules by allowing proxy posts in the For Sale forums, what's to stop a scammer from joining head-fi, getting involved in a friendly discussion in some thread, coming across as an OK guy, and then casually throwing out something like " Man, I'm dying to get a pair of "X" right now but I have to wait 3 more weeks before I can make even a WTB post.
" ? Chances are good, within an hour he'll have 3 or 4 offers from members being nice guys and willing to help him out by acting as his proxy "because it's OK to circumvent the minimum time/post rule in situations like this." Then, after laying their own reputation on the line to help the scammer out, they too become victims when the seller, going on the proxy's reputation, gets screwed.
Yes, this may never happen ... but it is possible and it could happen.
So sorry if we seem overly tight-assed about this sort of thing, but the rules are there for a reason, and we don't want them to be circumvented. Sorry to those who disagree, but at the moment, that's the way it is.
