Careful. I did this more or less by accident, with a main account, a porn account, and a goof off account. I didn't maintain a list of which ones had been banned from where and there were subscription overlaps.
One morning all of them - including the one that was 9 years old and had awards from participating in the first ever reddit gifts - got banned for "ban evasion".
Now I just make a new one every few months and distrust any account that can survive for more than a few years without getting banned.
So they encourage throwaways, but also ban you for using them.
