Now back to the subject, OP where are the "Personal threats"

I don't seem to find any !
It is your opinion. I have a different opinion. I believe that if someone writes me and promises that I will have at least 2 enemies (and he speaks on behalf of another person - as sergey1980 speaks on behalf of the markiz73), then I regard this as a threat and suspicious behavior.
Let's evaluate the facts you presented.
1.) Banned for plagiarism as markiz73.
There are thousands of banned users, trying to connect them this way is not smart.
2.) Miner as markiz73 and sergey1980.
Same as the point above, except for maybe hundreds and not thousands
3.) wx34scx, markiz73 and sergey1980 write a lot in the same topics.
philipma1957 and I always write a lot in the same topics ,it's because we share the same interest, it does not mean we are alts, it's normal for a group of people to always post in the same topic/s-- this theory is plain stupid.
4.) All three of them are very fond of serial scamer Smart Man.
I checked Smart Man's
profile, all I found was your negative feedback, along with some other random user's feedback, if he was a serial scammer wouldn't he have a type 1 flag or at least a negative from DT member? I do not understand the logic behind this accusation.
We have different opinions on this issue. You think that these are separate facts. I think they are interrelated.

If you do not trust them, then check own words of
Smart Man.
