I was just browsing /r/ukpolitics just now, and it is mind boggling how many pro-Israel comments come from people that apparently are only commenting about that topic. No activity whatsoever on popular subs, on hobby subs, but instead their entire posting history is composed of months and months of tirelessly defending the state of Israel.
Sounds like work, and it seems that many forgot about the Mossad-operated propaganda farms that made the news a decade ago. Most people are so blind to propaganda that these fake personas do not even have to be particularly subtle about it.
It would be so easy to identify these paid state actors with some simple code, but I do not want to give ammunition to those other cretins that would use such a tool to target Jewish people as a whole; so I just notice the propaganda and move on.
