"We have always appreciated the creative efforts of the PC modding community and we still fondly remember the awesome zombie invasion mod and original GTA map mod for GTAIV PC among many other classics. To be clear, the modding policy in our license has not changed and is the same as for GTAIV. Recent updates to GTAV PC had an unintended effect of making unplayable certain single player modifications. This was not intentional, no one has been banned for using single player modifications, and you should not worry about being banned or being relegated to the cheater pool just for using single player PC mods. Our primary focus is on protecting GTA Online against modifications that could give players an unfair advantage, disrupt gameplay, or cause griefing. It also bears mentioning that because game mods are by definition unauthorized, they may be broken by technical updates, cause instability, or affect your game in other unforeseen ways."
Modding and/or cheating in SP is completely safe.

Since people are reporting fresh bans recently, I don't know if you can definitively say that cheating is safe in SP.
I'll just believe Rockstar when they say that no-one has been banned for modding.
It really depends if using trainers counts as modding. It should, right?
I would *hope* they are going to leave SP trainers alone, as mods.. But the amount of people using injectors to fubar multiplayer is getting out of hand. That's why I'm a bit worried trainers are going to be categorized as something else, and not under the apparent blanket mod protection.
