please note that kakashi gifts are given away to any new account starting from the moment of its creation, and u don't have to sign-in on consecutive days, so if u don't login for the next 5 days and login on the 6th day from now will still be ur 3rd day to get gifts as an example. so not server related, it's account creation related. i clearly remember reaching lv 26-28 on my first day like Mr Qv too. so there is a high chance that the server is older than u think as Mr Qv said as kakashi login gifts are not related and not a proof of server up time. edit: about temari, that person he/she may have had the other ones of the following days, but doesn't have em on line up to be displayed to u (incase if the server is older than 2 days at time of taking that screenshot).

did u factor instances exp? and that stamina can be refilled with ingots?

i guess (not sure) that there are other login gifts for new servers like those of merges. have a nice day.
