A few days ago, I tried to post a new thread mentioning an iPhone app, Local Haze that I have created which displays the data from uRADMonitor sensors amongst other particulate matter sensors. It appears that it was never approved by a moderator and hence it appears to have just “timed out”? Are you sure that threads are getting deleted?
There were thousand of spam entries that needed deleting and Radu was MIA for a while so it truly got out of hand. I’d say that he dealt with it by wiping all entries from the start date of the spam. I ended up unsubscribing from all forums as the email account was getting bombarded beyond the point of sanity.
I’d say that your entry got caught in the clean up as it was listed (as the Last Post in the forum index) but the link was dead.
