Yup, this has happened to me several times back in high school, when all the shitty bands used to approach me asking to make a website. At first I was like "yeah, cool!" and then they automatically expected me to update it consistently and do things like handle merchandise sales. LOL. Yeah right. Then they get mad at me for not maintaining it. I'm like "I made the thing, you update it".
That was my lesson. I don't make websites anymore for people without charging thousands of dollars and an hourly fee for any future work.
