As others have said, you will want to diversify with alts. Maybe create some high profit non-sticker products on your alts and buy those with your main, to raise their creator level / sending limit. Then sell off of the alts via a combination of direct transfer + sticker method.
With sticker method, you buy stickers that your customers publish, but you can't buy the same sticker more than once and the sticker can't be other 99k ... or the account will get caught.
It might be worth buying grandfathered alts. Otherwise, you will need to buy VIP for your alts with prepaid giftcards to hide the identity of their owner.
Finally, make sure you are using a mafia made client and have scripts blocked in your browser, or IMVU's built in spyware will connect your accounts together as all being belonged to the same person.
