Thanks for reporting this. This is definitely not expected — there should be no redirects or gambling ads on OfflineTTS. I’ll investigate and fix it immediately. Appreciate you catching this.
Yes, it should be fixed now. The issue was caused by a third-party script that was triggering unexpected redirects for some visitors. I’ve removed it and verified that the site is no longer redirecting. Thanks again for reporting it.
My suggestion is to wait a week, make a deep analysis of the problem to avoid repeating it and post again.
