Strength Violation
This is very rare, but has been used in extreme cases. If your Proposal calls for the immediate destruction of all nuclear weapons and forbids their construction, and you list it as 'mild', it'll probably be deleted, so you should take a look at how Strength is decided.
Strong - Proposals that affect a very broad area of policy and/or use very strong language and possibly detailed clauses to affect a policy area in a dramatic way.
Significant - Proposals that affect a fair-sized area of policy and/or use fairly strong language to affect a policy area.
Mild - Proposals that affect a very limited area of policy and/or use fairly mild language to affect only that policy area, or broader policy areas in a very minor way.
