March 13-14 Forum Downtime - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Greetings:

As you probably noticed, the Forum was not working properly for the last 20 hours or so. I'm not sure how, but a couple of the files got corrupted. The good news is that they have been repaired and all is well again.

Thanks for your patience, and happy posting!!!!

Greetings:

An interesting result of the forum being down for almost a day is that since it has been back up and running again, the number of spam registrations and posts has decreased significantly. All I can figure is that the software bots and the heroin junkies that manually perform the registration (which requires visual confirmation of a code) must hit a seemingly dead forum and remove it from their lists. Maybe it would be a good strategy to shut the form off for a few hours once a month or so. I'll have to do a little Web research on the topic to see if there is any validity to my theory, or if it is merely a coincidence.
