Just read that thread and ..well that was a rather terse discussion quickly silenced by the mod.
My feeling is if you cant buy and sell hardware here then by rights you should also not be able to buy and sell services here, now if you want to do both of these via DMs privately then sure have at it but its a very slippery slope if they start allowing one but not the other they both have the same downfalls and problems.
Self promotion is also not allowed here so the allowance of buying and selling of services seems very odd when looking at the rules for the other two.
This really needs to be clarified by the owner of Vogons as it should be a complete blanket policy of no selling/advertising here of anything.
For clarity this is not about if people should or should not be paid for services, people should be compensated for their time and expertise but Vogons should not be a place to facilitate that much like its not a place to facilitate selling hardware items.
AI is inevitable, there is nothing you can do to stop it, no Ironman snap to save you from the Basilisk.
