Its not "fishing" . Its getting what you deserve .
It is neither fishing nor "deserved". He should charge a fee if he feels he deserves it for his service and be upfront with it. This way, the user can decide before hand whether to use him or not.
Hey guys, I have been in the forums for quite a while and I noticed that long transactions has been one of the most issues of users nowadays. I am offering a FREE transaction accelerator.

I know your service is "free" and all... but being here like 4 weeks and claiming to be a long term member while fishing for "tips", most likely by using free accelerators like AntPool and ViaBTC and confirmtx??
Are you suggesting he does not deserve the tips because of the free resources? I don't think so, as long as users a free to choose if they wanna tip or not.
