People would post even if they where cheating, and even cheating i doubt anyone would bother winning every game. Fair enough on saving, i guess saving regularly isn't that bad, 15 sounds like very little saves but actually if you try not to save often (not that i do) its more than once a month so doable.
The only reason I was suspicious was the cups, especially Carling, seen as knockout tournaments are obviously easy to cheat in by saving, though this has been mentioned in other threads.
not that i've won any cups (field reserves for FAT/JPT, try in the bigger ones), and I've just finished season 6, with Solihull Moors.
Personally the transfer thing, if you want to look at players requests for wages, you can without offering a contract. If you get gazumped, mess up your negotiations with a player etc, to go back and do them again is cheating. I've missed out on players before it happens. (esp when you wage budget is like 5k in L2).
Personally I'd add attribute masking onto this, and use the applicable rules for any other game I start, otherwise the player search filter can be very easy to use especially for free transfers.
