As you may have been reading, many persons have different reasons for using "Stealth Paypal" .
1. Remember though, the name of the forum is BLACKHATWORLD. Many of the marketing strategies may fall in a grey area that might put your funds at risk. To mitigate such risk, you may not necessarily want to use your personal account FIRST. More over, there are many strategies to making money here. You may opt to have different accounts for each strategy and then consolidate them after in your personal account.
2. There are those who are straight black hats, and so because of their activity do not want (really cannot) use their personal accounts.
3. This website has a global appeal with persons from many nations. Some of those nations either have paypal restrictions (example method of withdrawals) or no paypal at all. As such those persons would want to get an "stealth account" for that use.
4. Just because. There are those who want to have them just because others have it or it is available.
5. Experimenting. Whenever experimenting with new ideas and new areas, putting your account up may not be the best idea.
6. Dealing with PEOPLE on Web and Forums. Many people on the web are devious and may use black hat ways to pay you for goods or service, OR they may even pay you , and after they have given them what they want , they charge back. This will flag your personal account with unnecessary fraud activity, decreases your trust score with paypal and increases your risk factor. So using a stealth paypal for these type of transactions and then consolidating with your personal account after is one way of keeping your personal account clean.
BTW
@Henry Cooper $50,000 /mth in stealth is nothing. If you dont know of that happening, you in the wrong crowd.
