Twitter – How to access Twitter if the school has blocked it

I doubt you can do anything about most of these third party services, because they only create a profile out of what you have publicly provided on the internet in most cases. You can try complaining at these sites and request for a removal, but then that might open you up to more spam, perhaps? Revoking access would help only those legitimate app requests you have approved earlier.

My recommendation would be to use both, but if i had to pick one i would say a formal twitter account.

As you yourself noted in your question both the hashtag and account serve two very different purposes but work well together.

The hashtag is a great way to attach a subject to a tweet. Although getting people to use your specific hashtag can be a challenge at times.

A formal twitter account would allow let other twitter users engage with you ( or whomever is running the account ) on a more intimate level. While at the same time letting you broadcast and start conversations with other people.
