How can you tell if someone has more than one avatar on imvu?

You can often tell if someone has multiple avatars on IMVU by checking their account activity, such as recent logins or interactions from different usernames. Additionally, if they have a consistent style or similar friend lists across avatars, that might indicate they belong to the same person. Lastly, some users may inadvertently reveal their multiple accounts through conversations or by linking their avatars in profile details.
