Originally VTEC ignored the Save East Coast Rewards Twitter account even when I was posting positive things such as excellent service on the 18:19 to Newcastle. Then ^NB (now left and working with GTR) joined and started interacting and things generally became a lot more friendly. Then criticism due to the new website and catering lottery meant a lot more angry Tweets and VTEC seemed to revert to ignoring again. I care about the service on the ECML more than many which is why I spend way too much time on this! Those who've been around long enough also know I'm happy to be positive when things are done right, I don't think it's fair to just be critical rather than look at the positive aspects too.
It annoys me immensely if someone in VTEC tells the customer some incorrect information, I provide the correct information and because VTEC are ignoring my posts they continue to provide the incorrect information to future replies. I'm not saying trust everything I (or any others) post blindly if they contradict what you said, but use it as a prompt to double check what you've said and make sure that any errors are also mentioned to other members of the Twitter team (there seems to be a lot of common errors going round such as reservations close 18:00 the day before travel, hasn't been the case for many years, I remember even reserving a train for later in the day in GNER times. These days some routes even sell advance tickets on the day which require reservations).
VTEC do block their critics. I've been blocked a few times but always seem to quickly get unblocked but those accounts that are critical but only have a small number of followers (e.g. @vtecwatch) got blocked permanently.
