Poland’s antitrust and consumer protection watchdog imposed a fine of 106.6 million zlotys ($27.3 million) on PayPal Europe for failing to spell out to consumers in its contractual clauses activities for which they may be fined, UOKiK said on Monday.

UOKiK said that prohibited activities which could incur penalties were described in an unclear way and users may not understand exactly what was not allowed and what action the company could take in such cases.
