Proxies

so i just spent like 200 bucks on geo-targeted residential proxies for this german offer right. got my landing page all set up with german text, looked perfect. was using this provider that says they got 99 percent uptime and clean ips in germany. ran the campaign for two days, nada no conversions. not even a legit click. started digging and found out all my proxy sessions were getting flagged by the ad network. like the ips were from germany but they were from some weird ASN or the subnets...
