idk where u are getting your info from...? If you did this have your script immediately removed from SDN and you would more than likely be banned from osbot for SCAMMIN' the newbs that actually bought your first script before it was tested.
Anyways 1 time fee should guarantee that after "YOU" purchase a script it will run at least 1 month.
I don't care if the scripter gets hit by a bus 25 days after the purchase on a Thursday morning (right after rs updates). If the script isn't fully functional within the month the buyer deserves a refund. most of these 1 time payments are promised to be "lifetime" which shouldn't even be allowed because that's clearly false advertisement, none of these scripters will fix there scripts 10 years down the line.
All i gotta say to buyers is be careful which scripts you buy. And all i gotta say to scripters is if you are releasing a script and not planning on updating don't expect to be a SDN scripter for more than a week and you'r scripts will be removed.
Suggestion*** - New scripters should have some sort of tab, and until they prove they are not going to just quit on there scripts they don't receive pay. This will prevent people from releasing scripts for the first time, and quitting within the month. Essentially scamming a group of people and getting away with it should not be tolerated.
