ofuroinu, Possibly one of Facebook users could complain... Or Facebook blocked your website link. It doesn't depend on the Social Rabbit plugin, Facebook may block links for different unobvious reasons.
Unfortunately it's hard to reach Facebook support. Check please if you can add your Website URL in the post manually.
- You might try running your website through the Facebook Debugger:
https://developers.facebook.com/tools/debug/?ref=u2u
This tool was built to help to identify any errors that Facebook is reading from your website, and help provide information on what needs to be fixed to unblock your link.
If you see such an error, it means that your website has been blocked by Facebook:
From there, you can get help from the Facebook Developers team to make your website compliant and help their systems detect it as safe.
Click the link below and select "Get Started" to open a support ticket with the Facebook Developers team (this option may not be available for all websites):

2. Another way is to "Report a Problem"
To Report a Problem, click on the Help Center button in the top right corner of Facebook.
Select "Something Isn't Working" and fill the form about your blocked URL. You can include a screenshot with your report.
3. The third way is to contact
Facebook Ads Business support:
https://www.facebook.com/business/help
If you don't have Facebook Business Ads Manager account, please create this account first of all.
Open this link:
