I would really like to know this as well.
I haven't logged in with my alt since the announcement of coin games since I don't know what I need to do if I'm offered free coins with it.
Personally, I think known alts such as
https://www.warlight.net/Profile?p=50700156 https://www.warlight.net/Profile?p=374705005 https://www.warlight.net/Profile?p=4735479184 https://www.warlight.net/Profile?p=4736323931 https://www.warlight.net/Profile?p=6514192377 https://www.warlight.net/Profile?p=7636877711 https://www.warlight.net/Profile?p=9921932315 (and many more)
should be allowed, possibly after verification of the main account.
I'm not all that sure about hidden alts.
Allowing any alts in coin games may promote cheating however.
Looking at Warlight's continuing alt policy (and problems?), I have the feeling that there will be not much consequences (i.e. suspension, banning) for just using alts. I'm sure however that there will be when money is involved.
So even with the ToS as is, I think just fairly playing in a normal game with an alt account, or even alts together in the same team, will go under the radar anyway or fall under some sort of grace rule in the rare case of a report. After all, don't all map makers have alt accounts for their first map tests?
