@M.A.R.ಠ_ಠ I know nothing about the legal system of the USSR
There were different times in the soviet history - during some periods, you could walk naked in the streets. During other periods, you could be taken to a prison camp for showing up for work 15 minutes late.
But the questioner is clearly prejudiced, judging from his "merely anti-USSR cold-war-style propaganda" remark
In general, yes, everything now specifically allowed could get you into trouble.
My uncle created a kind of unofficial do-good club in his youth, and the matter was taken up to the local party officials when someone squeaked on them.
Because you could not create any kind of organization in the USSR without authorization from above.
Any kind of organization, starting from a postage stamp collection club, if created without authorization, was viewed as subversive.
On account of his stellar track reckord, my uncle was let go.
The local Party official told him that if this "letting go" becomes known in the higher ranks of the Party, this official might get punished heavily, but basically the official was willing to risk his career because my uncle seemed not "anti-soviet".
After the demise of the USSR, my mother told me that my grandfather had been taken prisoner during WWII, and escaped the day after or several days after.
This piece of information was only disclosed in our family to children once they reached about 16 years old, lest they spill this information to anyone outside the famly.
That's Soviet Union for you.
It was subversive even to be captured by enemy for 2 days, because - what if the enemy had converted you?
So when Putin said in the early 2000s that "the fall of the USSR was a catastrophe", I knew right away he was a sick fuck.
Like saying that the fall of the Third Reich was a catastrophe.
