Well, the title says it all, this player has obviously been using hacks and has no right to be in the Top Streak table.

Google search of his Steam ID

Crit hacker on hh 2 i think name nope using shortstop crithack

lol, 91 kills total, 91 crit kills as well, doesn't leave much in doubt.

What? I do that all the time! Thats perfectly normal

Interesting to see other communities have already banned him.

However, do we have enough evidence to support a ban?

I wouldn't say interesting, more like unsurprising, but I guess you must be kidding.

Take a look at one of the demos that was available from the Google link in the OP.

Or look at the name history in the steam profile of the person's account.

Looks like he's managed to get 91 kills and only died once in the span of 11 minutes.

Odd to see a crithack on the minigun, not sure how that one works. must've been abusing some other hacks too to not die so much.
