Those kinds of sites don’t really help with real karma. Reddit counts the numbers, but the comments still stay low because the activity looks off. If too many upvotes come at once, mods and filters can flag it as suspicious. If you use them at all, it has to be very slow and careful, otherwise you risk losing the account completely.The service I'm using now send upvotes and it count but my comments stay down and even comments that have less than mine are on top of me so I'm looking for a tested working one that rank my comments
