Here are the type of accounts you would encounter based on my experience.
1) Bots (Run by the site admins). These would message u with hidden messages, until you upgrade to a paid plan. After you upgrade they will not respond.
2) Fake profiles with fake photos run by scammers. Photos taken from social media accounts of attractive people. This is the largest group.
3) Fake profiles with real photos, run by scammers. These will do video calls with you, but ultimately try to run cons on you. This is second largest group.
4) People just looking for a hookup.
5) People actually looking for a spouse. Unfortunately this is a very small percentage of accounts, I would say less than 5%. Also majority of this group are people specifically looking for someone from USA for immigration purposes.
