Over 8 months, in 6 different Google Ads accounts : crypto exchanges affiliate marketing ads (NON-cloaked), but semi-blackhat.
And over 3 months, in 4 different Google Ads accounts : smm related ads (semi-blackhat).
Ofcourse, these are my exceptions, because in some Google Ads accounts, these niches can get accounts suspended quite fast. In a few accounts, in which they survive, I keep them going as long as possible, in which case, consistent billing is important, ensure it is postpay and the card added always has funds available for automatic billing, ensuring no automatic billing fails, then the longer surviving accounts remain safer for a longer period, also in which case, I do not "finger" or "tinker" the campaign, I just let it run.
