When I say recast it is in the context of someone who is copying the work of another that is still being produced by the original producer and is undercutting their sales. Second in that case it is typical that the castings are extremely poor quality.
I have a question that I hope someone in the know can answer. There are two ways for doing quality control. One is to inspect 100 percent and the other is to check a some random sample to check quality. Which process is used for model production?
Unfortunately recasters are only in it for a quick buck and are always poorly done. I remember following the figures for a while and the recasters had a lot of garage kit manufacturers quit because of the impact on sales and the poor quality.
Gotta agree that warning points should expire after some time.
The safest thing is to just stick with the modeling part of the board. It's too easy to get caught up in some of the other more controversial discussions and cross the line inadvertently.
As far as reporting threads if you stick to the modeling aspect of the board you're less likely to run into the inappropriate behavior of others which might warrant reporting.
