We don't actually lock the topic, the spammer does that themselves. They want you to read their method and install an userscript that will steal your data.
This is a trap of spammers from where they do this kind of work to steal various types of data. Those who fall into this kind of trap get their data stolen and later they are seen facing danger. That is why one should always be careful so that no one falls into such a trap.I've added some of their stuff to the anti-spam bot, so it should be better for a while. Please report the posts if you see them again.
If we see anything like this, we will definitely report it but here I have one thing to say that you should be more careful, you should mark the users who post such posts so that they cannot do any such work on those days, if they keep doing this then I think there will be a problem with reputation.
