Non-mage targets can usually be safely pulled without getting links by sending Carby in to fight and then allowing him to die.
Pulling mage targets that link must be handled very carefully. If a mage is in the middle of casting spells, you run the risk of everything relinking to the target once the do not agro or link timer expires after Carby dies. To prevent this, the SMN must be close enough to see if the target is casting. Once Carby has grabbed hate, he must be released when the target is not casting.
