The way to avoid or minimize account suspensions (of any type), depends on account creation technique. However, as many people have already stated many times, almost no one would so openly and freely share their techniques of creating working (GAds) threshold account and the reason for this is quite obvious. Example, a person who knows how to create working (GAds) threshold account would rather monetize his or her skills for example selling those accounts, or running campaigns in JV, etc. Another example, let us say someone is very good at something (like SEO), then that person would rather monetize his or her skills by selling SEO services and would not prefer to openly and freely share his or her SEO techniques. Another reason why people would rather not share such techniques is no one likes to saturate their working methods and techniques. That is why people openly share tips on campign creation, etc, but when it comes to creating working accounts, no one would share those techniques, and we cannot blame them, nor can we put a gun on their head and demand that they share such monetizable techniques.
Considering the above reality, I would suggest 2 things :-
1) Keep experimenting with different methods. Here is the biggest possible tip : Imagine you are a GAds review bot, what are all the things you would look out for if you want to catch churn & burn users. Think deeply for a whole day and keep making notes on a piece of paper. After that reinvent the way you create GAds accounts and keep experimenting.
2) You could try posting in "Hire A Freelancer" or "Want To Buy" section, mentioning that you are looking for a method to create GAds accounts with least suspension possibility.
However, do bear in mind, that GAds overall algorithms & GAds review algorithms always keep changing and accordingly the methods and techniques for creating working GAds accounts also keep changing.
I do understand if people do not openly and freely share things such as creation of working GAds threshold accounts : Because this is a monetizable skill and people spend a lot of time, efforts and resources for the same and very obviously such people would not like their methods to get saturated.
For example, I am not at all good in SEO and I have in the past, asked SEO experts to openly and freely share with me their SEO techniques, but they did not share any of their SEO techniques with me. I did not blame them, because I did understand that not everything can be openly and freely shared. Because such skills can be well monetized and takes lots of time and efforts to develop. At the most we may be able to help with things that can be openly & freely shared, like for example, me and many other members, very frequently openly & freely share tips about running GAds campaigns.
