If I read the rules, it is not banned at all.

courier new>Rule 12 Forbidden Weapons and Materials. The following weapons and materials are forbidden for use:....

and
courier new>Rule 12.2.1 Entanglement devices. Such as nets,....

So it seems there are forbidden, but if you read

courier new>Rule 12.2 Weapons or defenses, which tend to stop combat completely, of both (or more) robots. This includes, but is not limited to the following:
and then follows rule 12.2.1

My conclusion is, weapons which stops combat completely are forbidden for example nets. This is good rule. No combat, no fun.

But we have a cluster bot so only one of our bots is entangled. The other two can still walk around and attack.

Am I reading the rules correct or is it just me (from Holland as Geoff noticed )
What is your opinion?
