You guys dont understand the market it doesnt affect only me or you but himself.
Lets assume a company wanted to start a signature campaign and a manager tells that the average pay for hero/sr member is 100$/week and then the owner will say that I have seem people offering sig for 80$/month...
Now this will happen they will ask the manager to hire people with lower rates or simply post a thread with the lower rates and people will surely join and the amount which a company about to pay was 100$/week now will be paying a lot less affecting everyone.
This will also affect the OP because he van have that high paying sig then this.
Well, OP still has the right to make whatever offer he wants, they shouldn't care about influencing the market.
Besides, what's the chance that exact scenario really plays out the way you describe it?
One person offering lower rates isn't going to influence the whole market.
There are many campaigns that are already offering lower rates than that...
