I've been away for quite some time and I'll probably come back once I graduate. I still care about my bots, though (despite Monk being buggy as hell atm). I used to make use of Drive to provide the links, but I didn't know they would break after some time. What would you guys suggest me to do? Is the solution proposed above (fix script) sufficient for now?
Well, do not trust the modern hype i.e. a cloud. But I guess you already know it.
If you cannot host your bot yourself. Put it in the cloud, usually within a day or earlier appears at [archive]. Then just update the link to point there. I think, as of now, it is the most reliable way. Many thanks to Rednaxela for this effort.
