Spotcollector behavior


 

Has anyone else had my recent experience with multiple "spots" from a single callsign showing up in Spotcollector at the same time. In one instance a Polish station nearly filled the entire Spotcollector screen? This just happened again with two or three callsigns showing up, filling the page.
I do not think it is a Spotcollector issue per se but likely something from each of the Networks. Weird behavior, never experienced it before.

yea, something weird going on......getting a bunch of 80M spots for EU right now and its broad daylight there......and seeing the same thing, I'll get 5 spots from the same station, by 5 different stations on 5 different freqs.......and FT8 spots in the phone section of the band , I'm guessing something went belly up in the network.....

+ Yes: large number of spots of a single callsign on multiple frequencies - more than 10 - simultaneously, repeated for several different callsigns.

+ A persistent implementation of this would constitute a denial-of-service attack that would render the DX Cluster network useless. This vulnerability will persist until DXCluster operators gain the ability to revoke a client's ability to generate outgoing spots.

Thanks for the explanation, Dave I did crosscheck against the DX Spotting network on QRZ and it did not appear to be affected. Probably isolated to certain Networks and I just happen to have one or more of them as a Source for Spotcollector.
