There are several ways of creating one of these "bots" (Twitter robots, automated accounts) - you don't need to know how to program and you don't need your own server.
Probably the easiest way to set up such a Twitter account is to use the free IFTTT service (which stands for 'IF This, Then That'). If a website has an RSS feed (look for an orange square icon with a radiating white pattern) then you can use that to set up a system that will ping out a tweet for you.
You will need
- an input, in this case an RSS feed
- an output - a spare Twitter account
The steps are
- Create your spare Twitter account and log in
- Create an IFTTT account and log in there too
- While logged into both IFTTT and Twitter go to https://ifttt.com/twitter and activate Twitter as a channel (this will be your output) you probably won't need to activate RSS as a separate channel but just in case its https://ifttt.com/feed

Here’s what it looks like under the bonnet with the RSS feed as the
‘trigger’ causing the action of sending out a tweet. I’ve added the
hashtag #filmmusic and asked the recipe to publish this along with the
title of the update from Movies in Concert along with the address (Entry
URL) and the first line of the page. If you click into the lower box it looks like this and you can click on the blue ‘science flask’ icon to change the options, this will change what the tweets look like.
