Cresswell had missed the Millers last four games with damaged ankle ligaments and used the social network site to give details of his latest visit to a specialist.
“To be honest, I don’t like it,” said Scott. “We have a protocol and a code of conduct. He spoke about his injury in his programme notes but these ‘tweets’ were a continuation of that. I don’t really know what tweeting is but we have people who monitor it.”
Scott went on to express his lack of interest in Twitter and criticised those who use it.
“For the life in me, I cannot understand why people want to tell everyone what they are doing. They should be learning something worthwhile rather than telling everyone they are having a cup of soup!” he said.
“I am not a fan and it makes you realise that some people are so dominated by technology, they forget about what’s going on in real life.
“It amazes me that they have nothing better to do in life than telling people what they have just done,” he added. “I don’t think other people are interested but it becomes addictive. Go do some charity work instead. Don’t sit at home telling everyone ‘you’re bored’ or ‘watching TV’ or you have ‘just been to the toilet and it was great’.”
The Millers visit Bristol Rovers tonight seeking a return to winning ways after four consecutive defeats.
Scott was furious with his side’s performance in last weekend’s 1-0 defeat to Burton Albion and accused his players of not sticking to the ‘game plan’.
“We will persevere but we can’t let it affect our next performance at Bristol Rovers which is another really tough place to go,” he said. “There’s some tough games for the rest of this month and people have got to stand up and be counted. We will see whether they are men or boys.”
The Millers will be boosted by the return of defender Troy Brown from international duty but will not be signing former Crystal Palace defender Alassane N’Diaye.
The Frenchman, 29, played for the Millers reserves in midweek against Hartlepool but was substituted after just 45 minutes.
“I’d spoke to the agent who said he was match fit and ready to play which wasn’t an honest assessment,” said Scott.
“It’s disappointing when you get an agent who suggests a player but then the player turns up and it turns out his condition is completely wrong.”
