Spammers may be a problem but that does not excuse the inconsiderate part of not explaining the policy and where to post from the beginning. I always marvel at how spam is considered such a dire emergency and then look there are ads in between each post.
Spam clogs legitimate activity, the ads between posts help pay to keep this service up and running.
I think that the policies on minimum posts are a good thing, is it really that much to ask that you introduce yourself to the bitcoinTalk community before you focus on your own agenda? As someone who has managed forums in the past it is always a constant battle, on one had you do not want to alienate your user base by making your policies to strict, at the same time you don't want to spend all of your time on moderation.
If you have issues with the policy you are free to start your own forum
