How do you delete unwanted accounts from Tapatalk?

view story

http://forum.xda-developers.com – This is very annoying. I've sent several emails to the developer but they never respond. I got a bunch of accounts under my Tapatalk id just from opening forums from Google searches in it. If I delete the forum, it just comes back, some times instantly, other times it pops back when I come back. How do you get rid of them forever? Sent from my Nexus 4 using Tapatalk 2 (HowTos)
