George and Andreas:
Does Agora really want its boards looking like trash? Due to the multi-post spamming that is going on here, that is exactly what the PTSC board looks like to me even though I know its history --- it doesn't take much to imagine the effect on new folks that may be visiting for the first time. First impressions can be important.
Assuming the link provided in this spam is valid, the source is a company running a stock service called "Canada Picks Online". I realize Canada is a big place, but it seems that you would be able to locate and contact your fellow countrymen and ask, or take steps to require, that they stop this very irritating behavior. It is most certainly detracting to the great format that you have created here, and the forum members themselves should not be required to constantly "police" such antics day after day. People come here for discussion about their investment , not to see, or to be required to deal with, childish repetitive spamming.
Please do something about this using whatever resources are available to you. Thanks.
