there needs to be better rules against trolling,
Disruptive players can be reported

and manipulating the market,
No rules are needed. Supply and demand dictate prices. If someone sells something with a price way out of line that doesn't reflect the market, it will eventually return to a price that reflects the demand and availability of that item. it's a free market economy. People complain about undercutting and other such tactics in every MMO but the reality is, those tactics only work because something is too plentiful to justify the higher price. People are only willing to pay so much for an item and sellers are only willing to wait so long to sell. It is simple economics.

and trolling in the forums,
There are already rules on the forum for typical forum related issues. I'm curious what thread or post prompted you to comment on this.

The problem is, "trolling" accusations get thrown around far more often than actual trolling occurs. Just because you don't like a post doesn't mean it's trolling.


abusing people behind their backs to get attention.
This is a personal problem that needs to be worked out between the people involved, not something that needs to be regulated by the game unless it devolves to harassment which there are rules for.


all these people memorized the tos
Most people don't even read the TOS or user agreement. It is an extraordinary feat to specifically read the rules to find loopholes to exploit in them. The spirit of the rule is more important than the letter and any competent person at SE would employ the former, as it is always obvious when someone is trying to take advantage of the rules.

If you think someone is being harmful, you can report it to a GM. but we don't really need more rules.
