That's quite a wide problem to have, but let's go through everything step-by-step. Firstly, you should see if your accounts on r/WhatIsMyCQS have a low CQS (Contributor Quality Score), in which case Reddit will continue shadow-deleting your posts and comments since they have little to no trust of you on their platform. There is nothing to do about it except make unique and valid comments and threads (not automated nor copy-pasted) with natural posting intervals.
The second thing that you should consider is whether your automation tool uses realistic behavior and technical signatures. For instance, such things as random mouse movements and scrolling play an important role here, as Reddit is very keen on detecting bots and will simply ban your account due to its suspicious activity.
Finally, the third and perhaps the most basic aspect – proxies. What you really need are rotating mobile proxies; otherwise, any residential or datacenter IPs will be instantly detected as proxies. For example, FloppyData has good rotating mobile proxies which work fine on Reddit platforms. Feel free to contact me for further questions.
