actually yes.
There are payers who are using VPN (for personal use or just because it's a way to have access in fb, for some countries like China, Vietnam, maybe middle east or Turkey).
Those players when log in the game and at that time VPN is in a USA I.P., they can see some free vids and get boosters.
Many of them , just don't know that using VPN is forbidden from the game (forum members are just a minority comparing with some millions players and i don't know from where else someone gets a warning about VPN).
Those players with that farming can gather some sources but spending hours trying to find and watch only videos, hardly you can build a 7* team, maximum having some players 8* .
Unless you stayed some seasons in the same level and gathered some thousand packs.
Now with the reduced of free vids, it's harder.
So, they have good teams but not unbeaten.
Of course those players can be banned or find their teams one morning, without a single token or a pack.
The other category is players that use other methods.
A common method in Vietnam area is auto farming.
With the use of a program, you have your mobile active and searching for videos so the next morning you can find in your team some hundred packs or token.
Another method is buying packs or token with broken codes from credit cards.
Buying a huge pack with 30-40 $.
Some times there is also here in the forum some guys who are advertising "products" like this and we (the mods) delete them.
With those methods someone can build a team full of 9-10* players, 3 positions and special abilities at easy.
Of course this case is clearly a cheating and those cases are banned immediately - it's a straight red card.
Players of the game when they spot such players, it's useful to report them because nordeus doesn't have a bunch of people to hunt them every day.
(and they spread like mushrooms after the rain).
When we send a report, they take action.
Another category is players who believed that they found a method to "hack" the game.
If you google it, you 'll find some hundred or thousand sites (fb mostly), who are saying that can give you plenty of sources following some steps.
of course all of them are fraud.
And the last category is the token buyers.
ok, they aren't cheaters but some of them getting accused for that because they are from some Asian country.
If you read that thread (of #1) , you also must read my post/comment about how many cars MERCEDES and BMW selling in China.
To make it clear, all above are my thoughts as a player and a member of this forum (not even a mod).
