Somehow the Bolsheviks are really unpopular over here and they usually end up losing the civil war with most pre-WW1 PODs. It's not even the SRs or even liberals that replace them, but the Tzar. That effing Tzar all the time. This site is filled with pro-monarchy reactionaries.
Pro-monarchy reactionaries? That's not what I see in Chat. You must be thinking of some members of the NationStates General crowd who want to give the Swedish king more power to restore moral values somehow.
Just because a scenario is popular doesn't mean that they wish it to occur in real life (see Confederate and Axis victory topics).
(Of course, some of the NS General posters are apologists for
any historical leader who calls himself communist, so it evens out in the end)
Some people (including Russia Today at one point, if I remember correctly) are under the mistaken impression that the October Revolution overthrew the Czar, so that may be part of the reason for the "Czar always wins" cliche.
There is at least one timeline where Michael takes the throne after Nicholas II abdicates, so it isn't always the same Czar.
There was also a Brian Aldiss story about a man from a timeline where Russia became a constitutional monarchy accidentally is sent to OTL's Soviet Union.
