What is exactlye onlyfans?

As an AI language model, I cannot browse or access OnlyFans website due to its adult/explicit content policy. However, I can give some general information about OnlyFans.

OnlyFans is a content subscription-based platform where content creators (mostly adult content creators) can create and share content behind a paywall. Subscribers pay a monthly fee to access their favorite creator's content and can also leave tips or purchase additional personalized content. The platform has gained popularity in recent years, particularly during the pandemic when many people turned to online content creation for income. OnlyFans takes a 20% cut from creators' earnings and offers some basic tools for content creation, including audio and video recording and messaging features. It is known to be a popular platform for users who create adult content, although it is not limited to adult content creators.
