What separates the grades
Two grades sit behind this page: bot grade (5 services, from ฿350 per 1,000) — accounts made to move a number, often without a profile picture and usually without a guarantee; foreign grade (4, from ฿49 per 1,000) — mixed-country accounts, mid quality, some guaranteed. Every service name states which grade it is — that difference is what the 7.1x spread on this page comes from (฿49 to ฿350 per 1,000).
