'Lots' were in excess of 1000 e-mails.....
The last mail you were sent warning you of the imminent block explained exactly what was wrong:
Reason
You are uploading from HG612 Stats twice within the same minute every minute.
That was once at nn:07 and again at nn:11 secs and there was an explanation of what you might need to do.
Your uploads are now reinstated...
Edit:
At 21:59 you were still uploading using HG612 Modem Stats and still with the same duplicates (almost certainly two running windows processes). There is no sign of any DSLstats uploads.
