How exactly does someone have the time for multiple accounts/personas on here?

There are not as many as you would think that have multiple accounts but it is allowed .(or so I am told )
But most are used by people who have been blocked by someone on one account and use the second account to still harass them ,or comment on their own posts (thats sad actually )
But you are allowed up to 3 accounts
If I maxed out my pics or something like that ,I may consider that ,but it will get you banned to use other accounts to harass members that have blocked you .
That is specifically mentioned in the rules as one way to be terminated without warning

As The Who once said...."I wish I knew...I wish I knew...🎼"

For each of their personalities, lol.

i mean, multiple accounts i get. multiple identities, however, i do not.

why’s it so hard to fathom

Time management.

Not much of a social life, and splitting their time among all the accounts. They probably just use some of their accounts once in a while, if someone has blocked them, or they feel like catfishing someone, and have one or maybe two main ones.
