Ah, that makes sense, sadly.
You're using a JS element for the fancy post loading effect, and the ad blocker thinks that JS element is an ad. That is sadly common, and incredibly frustrating as ad blockers become more common.
1. Reporting the problem to the developer of the ad blocker.
2. Asking those with trouble to whitelist your site in their ad blocker (they understandably might not do this, because ads, but it's the only way for them to keep using the ad blocker and view your site if you keep the post loading effect).
3. Consider getting rid of the fancy JS post loader effect. If it's a JS element that is required in order for content to be viewed, chances are that ad blockers will block it again in the future.
