Not enough history yet to chart a trend.
How to reduce this
Official fixPostHog offers a free managed reverse proxy: route events through a subdomain you own (set api_host and ui_host in the SDK) so requests come from your domain, not posthog.com.
Official PostHog docs → blockrate's own first-party reporter already forwards events from your domain.
