How can one get a free upgrade on Adult Friend Finder?

As of the last update, Adult Friend Finder typically does not offer free upgrades to premium membership levels as their business model relies on paid subscriptions. The platform often runs promotions and offers temporary discounts or trials that one can look out for, but these opportunities are usually open to new members as a way to entice them to join. To increase the chances of getting a better deal or an upgrade, one may consider subscribing to their newsletter, engaging actively in the community, or checking for promotional events. It is also prudent to frequently check their official website or contact customer support for any undisclosed offers. However, it's important to remain cautious of third-party claims offering free upgrades as these might be scams or lead to unauthorized charges.
