Generally speaking, most online sports betting sites, online casinos and other such gambling sites will restrict you to just one account per person. This is to prevent things such as fraud, scams and bonus abuse. It is often the case that you’re allowed more than one account per IP address or household. However, bonuses are usually restricted to one per household. There are often exceptions to the rule though. To find out Betfair’s stance check out our review at CaptainGambling.com.
