Stars 25+2 Turbo 9-handed. I can't understand bubble call.

Hello,
I posted some time ago an hand where I was spite called.. (before posting I didn't know the 'spite call' concept..)
I had many spite calls this period, but someone is really unexplainable for me.

Final Pot: t3878
He won it with 9To

I'm pretty sure I didn't give impression to push ATC. I folded to him LOT of times with a wide pushing range because of terrible cards...
It was not a misclick.
He activated the timer, thinked about it and decided to call.
I really can't find how this can be +EV or a spite call.
I add he's a winning semi-regular.

Maybe people know I lose allins whatever I hold ? [img]/images/graemlins/smile.gif[/img]
I would appreciate your comments.
Thanks
