So since you did not provide any specific time-stamps I watched the entire replay looking for suspicious movements
1:45 titan starts heading towards middle right before he pearls, a bit suspicious.
9:20 titan finds lumber base bottom right of map without scouting it first, a bit suspicious.
Since you said 10:00-15:00 i'll start from here.
10:09 titan pearls top middle right as goblin finishes making his lumber base, kind of suspicious
10:26 3 of the titan's minions walked right by the goblin without even hesitating, if titan did map-hack it would have been an easy kill, makes me think he doesn't mh
11:24 titan finds goblin workers at bottom left of the map, it is a bit suspicious he would find them there but at the same time, murloc had a seed close by to it so titan could have been pearling for that, the titan also scouted like 3 lumber bases in wind-walk before he found the goblin's workers.
12:55 the 3 minions find the ogre's lumber base at bottom right of the map without scouting it first, kind of suspicious.
14:24 titan pearls top right area where the goblin was walking towards, I'm sure you thought this was suspicious since you mentioned it in the game, but that was like the 5th time titan had pearled the top right area, the first few pearls there were blanks, top right and euro were definitely the two most pearled spots for this titan.
14:48 titan walks south in wind-walk while goblin walks north, in very close proximity, but if titan was map-hacking seems like it would have been an easy kill on the goblin right there.
16:32 minions kill the goblin at the shop, I'm sure you thought this was very suspicious as well, but titan had just pearled around the goblin a few seconds ago and it gave vision of the goblin attempting to jump on the ramp. Now if this were some noob titan or pub player I would have thought this to be pretty suspicious also, but considering this guy isn't and had vision of you attempting to jump right before you did, it makes it seem less suspicious to me.
Now my overall thoughts after watching this replay over and over again for a couple hours. In my honest opinion, based off of this one replay I do not think the titan map-hacks for a few reasons, the way the titan scouted the map with his main and minions (they were constantly roaming the map, and walking into blank areas most of the time, but walked to a couple lumber bases without pearling), the titan was constantly pearling the map and like more than half of the titan's pearls were misses, he even missed out on a few kills that would have been super easy if he was map-hacking, and this titan isn't some noob or random pub player (probably would have been considered top 3 best titans of 2015). In my opinion there weren't any obvious map-hack plays so I would usually deny this request, but this guy is a good friend of mine and I don't want anyone to think that I am being biased here, so I would like some other Island Defense moderators/admins to review this, give their input and process it them self.
@haunt @av1onSide note: I already banned that satyr for map-hack on his other aliases last night. That satyr is a really obvious map-hacker.
