I’m not sure that it’s reasonable to finger a particular site as a problem if it works for other people in other browsers.
No idea about Safari anymore as I gave up on iDevices a couple of months ago, but was getting annoyed with being continually redirected to the AppStore to buy ‘Game of War’ or whatever the schonky ad in the sidebar was trying to push. I actually stopped visiting from my iPhone and started just using a laptop.
Chrome on my Android was pretty nasty for a lot of sites. Firefox worked reasonably well but I settled on Dolphin for now. It works well and STW behaves on it when I’m logged in. Firefox again for pref on a Windows laptop, which has been behaving for weeks. Having said that though, I turn off the ads, which i’m allowed to do.
I’d say it’s more that Safari/AppStore as a combo is being targetted for driveby ads…
