There is no safe method
I have been trying hard and it sucks big time.
Accounts get ghosted, suspended, deleted, even if you use private proxies, don't link to anything, make nice profiles.
Also, if you try to link directly to a sponsor, it gets 404 or redirected
Url shortner gets the same results, even new and/or underground ones ! One spam complaint, BANG, the new url shortner that you thought would last long gets banned.
Want to use your own blogs/sites ? It will get the same result after a while
The only solution.
Real accounts, one account per proxy (could be spread thru private proxies, some of mine still stand since i work this way), lots and lots of sites with various sponsors (not the same ID link on those sites).
You build up accounts and pray you don't get the hammer after a few weeks/months before you even had the time to make ONE cent
