When adding some feeds (e.g. FreewareGenius feed: http://www.freewaregenius.com/feed/) instead of adding the original feed, the whole subscription gets reset into some arabic-like site with the address at “thendral.blogspot.com” and the respective feed.
This issue has already been reported over 6 years ago at getsatisfaction.com forums, but apparently it’s been still appearing ever since.
no problem! this did not require a dev fix; it’s doable by us users. i clicked the dropdown arrow for the feed and went to site settings, then pasted the correct feed address you provided in the “RSS/XML URL” field and hit the parse button.
if there are a lot of feeds redirected to that thendral site, though, it would need a dev to run a search to develop a list of them and automate the correction.
