We have been “discovered” by a very aggressive spammer company from Shenzhen area China, claiming to produce PCBs professionally. Despite several friendly warnings, the spam frequency of these emails has increased up to 12 hours before effective blocking.
Therefore all the following addresses have been definitely spam blocked:
- *@163.com
- *@jsdpcb.com
- *@jsd-pcb.com
- *.cn addresses, likewise
We recommend to not engage in any business with this company, as their services were evaluated as of no value and their staff turns out to be unprofessional or non-responsive at all.
