Try to use 
if(!usr in M.IgnoreList)


I don't know if that works.

IgnoreList is set to something other than a list(), likely null.
Wherever you have declared it make sure it is initialised to something like:
IgnoreList = list()

Try to use
if(!usr in M.IgnoreList)

I don't know if that works.

Due to how order of operations work in DM, that won't work. It should be...

if(!(usr in M.IgnoreList))

In response to LordAndrew (#3)
Using list.Find and using if(!(usr in list)) both do the same.
