Akhtar was cited, yes. So was Lee. So far as I know, neither have been suspended, they were both cleared. Yes, people raise questions about both their actions still, mainly when they're trying to play mind games or score points in BS arguments like this one.
I've never seen Shabbir bowl, so I can't comment on whether he's suspension was fair or not, but as far as I can tell, the ICC followed its normal procedures and found he needed to remedy his action. What's objectionable about this?
The doosra for a off-spinner involves a different biomechnical movement to a regular off-break. That's why its often a throw when the normal off-break isn't. A yorker or bouncer is the same biomechnical action, merely a different release point.
If your channel 69 reference is talking about the Warne pitch reports, your response is a cop out from debating the facts of the issue. I'm not defending what Warne did, but I'm saying I don't think it amounted to a criminal action or can be considered the equivalent of match-fixing.
