REUTERS - Mar 5 - Cupid Plc's profits rose 31%. Cupid Plc reported pretax profit of 9.2M pounds ($13.9M), compared to 7M in 2011. Cupid said it wooed 1.78M new subscribers to its websites last year, with particularly strong growth in France and the U.S. Revenues for 2012 increased by 51% to 80.9M pounds. Cupid's share price slid ~28% in February, the biggest monthly fall since the company was floated on London's junior AIM market in June 2010. Last month, the BBC published a report featuring claims from members who said that they suspected that fake communications had been used to encourage them to buy subscriptions. Cupid denied the claims and said that it only acted "in a legal and appropriate manner".
