I've had the Tap-a-talk module enabled for ages now, why the sudden complaints now?
Dave, Tapatalk authors are getting very aggressive in turning your forum into advertising machine for their app.
If I go to the forums from an iPhone it keeps popping up a request that I buy tapatalk, even if I deny it every time.
And the "Sent from my $CRAP using Tapatalk" spam is extremely annoying because it is not delimited like a signature and in the case of oneliners this spam makes 50% of the message! Reading discussion thread where every other message ends with this spam crap is really ridiculous. Just look at the threads BravoV pointed out. Imagine everyone would be using Tapatalk.
Don't you find third party shoving up their paid app up your readers asses using your forum offensive? I do. It's not like anyone needs Tapatalk to read the forums, or you getting anything from this annoyance.
On forums I care for (forums.bistudio.com running vbulletin) I had rage disabled Tapatalk because of this and occassional technical errors it was causing.
