You cant stack rabbadons, most item effects cant be duplicated by purchasing the same item. Sometimes different items with the same effects cant have the effect stacked
. You have to read wether something is a passive or a unique passive.
When an item has a "Unique passive" they cannot be stacked, meaning you won't get the effect of that Unique passive more than once. If they just have a regular Passive effect then you can stack them, hence why people used to stack Doran's rings before their passive was changed into a Unique.
