Looking at shares owners accounts is not so hard on Picostocks pages - just click a person's name.
There is a person who started on 15th July 2013 and bought 150 shares for 0.395 BTC each.
(Next transactions were a bit strange: https://picostocks.com/users/transactions/921/page:44)

Now the person owns 3116 shares, which equals to about 10-12 BTC ($2100-2500) in current prices.
(One should earn more from keeping then than from selling, it may be even 20 BTC or more, as difficulty won't grow much when bitcoin price is low.).

The total invested money (58 BTC x $80/BTC = $4640) minus the current value (above) gives a loss around $2300.
(If BTC value goes up, the loss will be smaller.)

The loss is not big enough to justify going to courts. The lawyers would cost much more.
Crying here is cheaper and similarly effective.
