It started after I left message in the topic dedicated to the markiz73 ban appeal:

Smart man is involved in:
1.) Mass account trading.
2.) Merit abuse.
3.) Bumping /shilling.
4.) Offering bumping service.
5.) Plagiarism (many accounts from his farms are banned for plagiarism).
6.) Participation in the obvious scam projects.
7.) Account farming.
etc.

I received a personal message from sergey1980 Screenshot

as indicated in the post, look carefully.

I do not take part in your battles, so please do not transfer your fights with the Smart man to this topic.

After I refused him and showed that he was lying, I received the following message:

Lie. https://bitcointalk.org/index.php?topic=5105163.msg51451682#msg51451682

ok. I just did not understand what I or the markiz73 hurt you.
As a result, you will receive at least 2x enemies.
I am always for peace, but if you want another, do not be angry.

Then we had a short conversation (if necessary, I will provide screenshots and translation, but I do not think that it will be necessary because it is impossible to dispute the facts that are stored in PM) and I was surprised to learn that:
1.) According to sergey1980, Smart Man is not banned for a scam, so everything is OK with him.
2.) sergey1980's goal is to unban Russian participants from the list.
3.) I will get two enemies - the markiz73 and sergey1980.
4.) sergey1980 is not a fan or hater of Smart Man, rarely intersects with him, and in general does not exactly remember their relationship.

I was surprised by this nonsense:
1.) No comments
2.) I think we need to fight for the purity of the forum, and not for a handful of users connected by language or other grounds.
3.) I wonder why he writes on behalf of markiz73? Roll Eyes

4.) The obvious lie. 7 from total 11 merits was sent to Smart man. And he actively defended this scamer.

As I said, all this surprised me, so I decided to look at these users more closely.
Very quickly, I discovered interesting facts:

markiz73
Favorite profiles to send sMerit to
Profile      Sum
Smart man   15 - top1
sergey1980   12 - top2
wx34scx     5 - top4

sergey1980
Favorite profiles to send sMerit to
Profile      Sum
Smart man   7 - top1
wx34scx      1 - top2 (as 3 another users)

wx34scx

markiz73      2 - top1/2
Smart man   2 - top1/2

Who is wx34scx?
1.) Banned for plagiarism as markiz73.
2.) Miner as markiz73 and sergey1980.
3.) wx34scx, markiz73 and sergey1980 write a lot in the same topics.
4.) All three of them are very fond of serial scamer Smart Man.

sergey1980 not banned, so he obviously managed to clear the history of his posts - 144 posts deleted. With a total remaining quantity of 291. But the information that is enough to draw conclusions about him.
I think his behavior suspicious and not trustworthy.
