If you're trying to find a way to screen out bogus or low-quality social media accounts for your contest, EasyComment could be just the ticket. The service is geared for social media influencers and content publishers who want to run sweepstakes and other promotions on Instagram, Facebook, Twitter, YouTube and TikTok. EasyComment has a range of filtering options to screen out low-quality accounts based on things like duplicate comments, particular words, hashtags and mentions, so you can pick a winner without a lot of hassle.
Another option is Verisoul, a fraud detection and prevention service. Verisoul automates the screening for fraudulent activity like people signing up multiple times, bots and account takeovers. It assesses a variety of signals to determine whether each user is legitimate and unique, including device risk, proxy detection and phone and email intelligence. That means it's a good option if you want to keep fakes out of your contest.
If you're looking for something more geared to content protection, check out Loti. Loti is designed to spot and remove infringing content and deepfakes, but it can also be used to screen out bogus social media accounts. Among its features: daily scans for fake accounts and endorsements, so you can be sure people entering your contest are who they say they are. Loti also has a licensing platform for content control, which is useful for public figures and influencers.
