With regards to the 2ch viewer(maru) handled by N.T. Technology, we have noticed that recently, there have been many people obtaining large numbers of IDs fraudulently and misusing them.
Please find below the list of IDs which have been invalidated due to inappropriate actions on 2ch using the viewer.

I believe you know the first 8 digits are the same for the IDs used.
These people are using large amounts of IDs (so large an amount it is difficult to believe they paid for them), which they cease using after a while, and are using scripts to fill up threads for hours a day.
Perpetrators of such acts are declaring online that they "did not pay but are using large amounts of IDs obtained fraudulently", and we have yet to come up with any solution.
Due to continued spamming,the servers of 2ch have been overloaded.
2ch has adopted several countermeasures but with regards to fraudulent procurement of IDs, there has yet to be any conclusion.
Please carry out detailed investigations and put a stop to the fraudulent procurement of IDs.
