These pools are all scams, merge mining isn't currently possible with anything other than a few SHA256 coins.
Its definitely not a scam.
Kindve annoyed tho. Pool op had LEAF coin listed as merge mineable and now it has disappeared along with the profits it would have given. Making this no more fruitful than a multipool.
I think there is a serious future in scrypt merge mining. Markm made me realize this the other day.
