I agree with this. Looks like his posts weren't bad, either. There are actually intelligent people on this forum who can think quickly and write something constructive quickly, and that's a lot different than the average shit poster. Yahoo62278 has a stellar reputation as a campaign manager, and Im sort of surprised he's denying you payment. I can see him kicking you out, but you did give them advertising regardless of the timeframe of your posts.
There are distinct differences between:
1) Desirable vs. undesirable behavior.
2) Posting quality.
Real assessment of a user can be actually far more complicated than the newbie/random/half-baked campaign managers make it out to be. There are far too many factors to consider which range outside of the scope 'quality vs. quantity'. I absolutely see no reason for which the OP should be paid. Do you see a clause somewhere which guarantees payment if you reach a certain post count?
In my case, you'd have to be overly constructive for me to even consider letting you stay after post-bursting. Usually if I catch you doing this, you're permanently banned from Bitmixer (which means that you get denied payment for any unpaid posts). This also means a permanent placement on the SMAS list.
0xfff seems to basically be a shitposter anyway. The posts that he did in bursts are all just barely reaching any minimum amount of characters and are clearly done with the intention of getting the posting over with as quickly as possible. Even without post bursting, I would be surprised if any legitimate campaign manager kept him in for long at all.
If your posts are vaguely readable and have decent English grammar, that doesn't make them good. Users who aren't in a sig campaign tend to post a variety of lengths and arguments for different topics - anyone in a signature campaign who isn't a spammer should at least feign that variety while posting on topic, and preferably have it naturally.
Regardless, managers obviously have the right to remove any user at their discretion - that's just common sense and is stated on nearly all sig campaign threads. Withholding funds is not a scam when it's someone else's funds rather than your own and you knew that there was no guarantee you would receive their funds.
The manager also has no connection to the Yo-Ex exchange. The exchange's perspective is that they hired a trustworthy community member to escrow funds and manage the campaign for them (which they did).
