You may find the reason in ToS and/or in Community Standards violation.
My assumption is that your Gig might have mislead the Buyers.
See clauses from Community Standard that you might have been breached imo.
Fake engagement and traffic
Do not post, offer or ask for:
- Followers, subscribers, fans or views on social media platforms.
- Fake engagement on any platform.
Promise a service outcome which is not in your control
In certain instances, sellers may be tempted to promise outcomes of their service which is not in their control. For example, guaranteeing to restore your Amazon account or promising an exact amount of viewers for a Youtube video by its digital promotion. Please refrain from promising outcomes that are not in your control because it misleads buyers.
This is completely wrong way of thinking. Your argument that other Gigs violate rules is no excuse to create another Gig that violates the rules.
