Is this legal?

So i saw few of mine friends making new accounts,boosting them to lv 10 and then sending 375 rp skins/icons/wards as gifts to their main account. They are using many IP adresses(pub places,their home IP adress...).I though that first 400 RP is not giftable but it seems Riot changed it. Im against this.
