For one, ES already goes through most of the threads made here and there isn't much use in making the same thread again in the form of a petition.
Also, these threads contain a lot of "sign" spam posts.
Apart from the fact that ES has already stated that petitions are not really going to make them change anything there is also the danger of having petitions now on everything.
As a result, the staff of AoE3H and HG has decided to close the current petition threads and not let any new ones be made. It is perfectly allright to have a dissussion on a topic, just NO Petitions.
Some petition topics are actually useful discussions, such as the Realistic Ship Movement one. The thing is, the thread gets shot down by posts that simply say "signed" and doesn't contribute much to the discussion. If we simply discuss these things ES will read and decide on what they find better, as usual.
