It can, yes.
Is there any precautions to take or any way to stop it?
Yes the only truly irreversible payment method is Bitcoins. Many users have a Bitcoin wallet so I suggest you only accept payments through Bitcoins.
Yeah, but it's hard to do that because 90% of people don't know how to use BTC :\
Chargeback – a reversal of funds on a transaction initiated by the issuing bank. Chargebacks apply for card payments as well as German Direct Debit (ELV) payments. Most common reasons the issuing bank will initiate such recalls are non-delivery of product or service, payment not authorized by card holder or the item delivered is not ad described.
Chargeback Reversal – chargebacks can be objected by providing supporting information on product being delivered, transaction authorization, etc. If the chargeback objection is successful, a Chargeback Reversal is received from the issuing bank. There could be two Chargeback and Reversal cycles for each card transaction.

That's actually kinda sad.. Bitcoins eliminates the possibility of being scammed by chargeback; which is one of the most pulled of scams on virtual marketplaces. We should educate people on Sythe about Bitcoins hehe.
Below taken from the Skrill website. I heard you can buy protection from chargebacks, but that hardly seems worth it.
Attempts have definitely been made. [Example 1] [Example 2]
