Firstly you do not even have up to ten activities yet and you want to start advertising for ico how sure are you that they are not scam why not understand the forum and build yourself before you venture into all this.
Their account doesn't need to be trusted in the community for them to be reliable, the trust and assurance will always come from the escrows and campaign managers being used by the ICO developers not themselves. Also there are other aspects to consider if an ICO is a scam like the their whitepaper and their team, and judging them solely about their rank in the forum is not one of them. If we go to what you believe in ICO opportunities will always look like a scam as all of their accounts are low ranking members of the community.
