No . There is no "report to mods" option on a mobile version . I do all my reading from my phone and I too noticed the spam this morning but just go on to parksys email address and email him ; and it was gone within 2o minutes .
Thanks for the email and to all who take the time and trouble to send me a heads up when something untoward appears on the message boards.
I can usually do a spot of moddying from my mobile phone but if I need to edit something it's much easier from my laptop computer
