AA Staff are not stupid to give invites to those who have been there for so long, they check all the logs, how many cheats of theirs you have used, your forum activity, and so on, and their EAC cheats never been detected for almost a year now, and yes you cant just go there and get into the private cheats, it takes time, there are so many members asking to get in and they are being denied [ by giving purpose of the denial ].
But there is Elusion, proofcore, if you really care for your main account and dont want to get hit by a ban hammers then try stick with the very private providers like i mentioned, if you just going with EA pro play which is 15$ then you can get a public BF cheat that you can find in here
Note: Over the years AA staff did really catch rats and dealt with them, thats why now they only give invitation to their really loyal customers who are known over the years, and their private cheats are not for sale in the first place, its just on the house for being loyal customer and following the rules, i am one of the lucky ones, and i can say i never had issue with their EAC cheats, as always most of the bans being caused by user side, i have used their apex, playing as closet very carefully and never had a ban, and for testing purpose i went full rage lol, and i got manually banned, its obvious.
